1. Preface

The rapid development in the field of basic materials has brought major changes to the social, economic and cultural systems of all countries in the world. As an important category of advanced basic materials industry, since the implementation of the "13th Five-Year Plan" series of strategic measures, China's magnesium alloy material industry has independently developed more than 10 kinds of magnesium alloy materials and successfully applied in aviation, aerospace, national defense, military, automotive and other fields, greatly reducing the cost of magnesium alloy products and improving the market competitiveness of products. China is rich in magnesium resources, stimulated by the demand for automobile energy saving, emission reduction and lightweight, which is expected to promote the further development of the consumption market of magnesium alloy materials, bringing opportunities and challenges to the development of the industry.

Keeping up with the global trend of green energy conservation, China's magnesium alloy material industry as a whole is developing in the direction of low energy consumption, high efficiency and high quality, and is constantly undergoing industrial upgrading. China's magnesium alloy materials related process technology research started later than the developed countries in Europe and the United States, although a number of core and key technologies have broken through in some magnesium alloy materials, but there are still large gaps in research and development efficiency, production quality, market expansion, environmental protection and other aspects. In the future, China's magnesium alloy material industry needs to take the national strategic demand as the benchmark, keep up with international research hotspots, and strengthen the research and development of advanced magnesium alloy materials while continuously improving the overall level of the industry, and strive to improve the independent innovation ability. By optimizing the organization and implementation method, it can help the "production, university and research" system of advanced magnesium alloy materials urgently needed by major national projects to smooth the channel, promote the transformation of relevant scientific research achievements and realize the industrial application, realize the strategic transformation of China from a material country to a material power, and meet the needs of advanced magnesium alloy materials for the national economy, national major projects and social sustainable development.

2. Development status and problems of advanced magnesium alloy material industry in China

Part.1 Development status

1. Magnesium alloy material industry upgrading trend is obvious

Since the "13th Five-Year Plan", China's magnesium alloy material industry has implemented the independent innovation strategy, and closely relied on scientific and technological progress and technological innovation to improve the uniformity of material quality, effectively improving the effective supply capacity and level of the high-end material industry. Under the new normal, China has gradually changed the traditional model of high input, high consumption, high pollution and high emission, and transformed to the development model of low input, low consumption, high output and low pollution, and new processes and methods of short process, low cost and low energy consumption have been emerging.

2. Original magnesium production capacity and market consumption

In recent years, the overall operation of magnesium industry in China is stable, and the output and export volume continue to increase. At present, the global raw magnesium production is mainly from China, according to the statistics of the China Non-Ferrous Metals Industry Association, in 2019, China's raw magnesium production was 9.69×105t, an increase of 12.2%; In terms of price, affected by the increase in supply, the average price of original magnesium was 15,949 yuan /t, down 3.3% year-on-year, and the actual profit level of magnesium smelting enterprises decreased slightly year-on-year; In terms of resource consumption and market, the consumption of magnesium resources in China was 4.85×105t, an increase of 8.6%, an increase of 1.6 percentage points compared with the same period last year, but the demand for magnesium resources in foreign countries rebounded, and China's total export of various magnesium products in 2019 was about 4.52×105t, an increase of 10.2%. The export volume accounted for 46.6% of our country's magnesium output.

3. Magnesium alloy material industry technology research and development progress

In recent years, in view of the international weakness of magnesium alloy materials with poor mechanical properties, China has actively carried out the development of advanced magnesium alloy materials, and made important breakthroughs in the engineering technology of rare earth magnesium alloys, large size casting rods and large complex parts. Some of the large-size complex castings of high-strength magnesium alloys and large-size extruded profiles/forgings of high-strength heat-resistant magnesium alloys have reached the world advanced level. Specifically, in 2019, Nanjing Yunhai Special Metal Co., Ltd. made significant progress in technology research and development and production integration, and the forged magnesium alloy wheels produced were applied in automobile host enterprises. The National Engineering Research Center of Light Alloy Precision Forming of Shanghai Jiao Tong University has developed a new type of high-performance lightweight magnesium rare earth alloy material, which has been successfully applied to the key complex load-bearing parts of helicopters, with remarkable lightweight effect, and has achieved batch and stable manufacturing, filling the gap of high-strength heat-resistant magnesium alloy materials for a new generation of helicopters in China. The National Magnesium Alloy Material Engineering Technology Research Center of Chongqing University has developed more than 40 new magnesium alloys such as AT, AE and VW series, of which 16 alloys have become national standard grades, and more than a dozen alloys have been applied in engineering and promoted in industrialization. Northeastern University has developed the production technology of large-size magnesium alloy flat ingot, which can produce magnesium alloy flat ingot with a maximum cross-section of 1450mm×400mm at present. A complete set of rolling technology for magnesium alloy wide plate and coil has been developed and applied in industrialization. Central South University and Changchun Institute of Applied Chemistry have developed high-strength and high-toughness rare-earth magnesium alloy, high-performance die-casting magnesium alloy and rare-earth magnesium alloy mass production technologies, which have been successfully applied to aviation, aerospace, national defense, automotive, electronic products and other fields, greatly reducing the cost of rare-earth magnesium alloy products, enhancing market competitiveness, and filling the gaps in related fields in China.

Part.2 The main problem

1. The industrial development started late, the foundation is thin, the import dependence of key equipment is high, and the phenomenon of being subject to people is prominent

China's high performance magnesium alloy material industry started late, the foundation is thin, and the application is still in the industrial chain and value chain in the middle and low end. At the same time, the implementation rate of relevant strategic policies is low, the gap between key process technologies and foreign countries is large, and high-end equipment mostly relies on imports. The technology and equipment required for research and development are often subject to foreign export restrictions, which makes the research and development of magnesium alloy materials difficult, especially the research and development of many high-end core materials is difficult, performance improvement is slow, and production capacity is seriously insufficient. In addition, the intelligent level of research and development, production and service of relevant enterprises is low, the support system such as standards, testing, evaluation, measurement and management is missing, and the stability of product performance and quality consistency need to be further improved.

2. The scientific research system is not yet perfect, the R&D investment is insufficient, and the construction of talent team needs to be improved

At present, a sound scientific research system is lacking, the enterprise-led research and development mechanism still needs to be further improved, and the "industry-university-research and application" cooperation is not close, and there are still barriers to integration. The research and development investment of relevant research institutions is small, the construction of talent team is imperfect, the lack of incentive policies and research and development platforms, and the lack of innovation motivation of scientific and technological personnel. In addition, there is a lack of protection policies for new technology investment risks, and new technologies of scientific research institutions are difficult to be promoted and applied in enterprises.

3. Deep-seated contradictions and problems such as structural overcapacity and market supply and demand imbalance in the magnesium alloy material industry have gradually emerged

Affected by changes in the international and domestic economic situation, especially the global novel coronavirus pneumonia epidemic, the market demand for metal materials is depressed, and deep-seated contradictions and problems such as structural overcapacity accumulated for a long time in the magnesium alloy material industry and market supply and demand imbalance have gradually emerged. At present, the overall operation of China's magnesium industry is stable, the output and export volume continue to grow, but there are shortcomings in the level of smelting environmental protection and the application of deep-processed products, and the task of industrial transformation and upgrading is still difficult. In addition, China's magnesium alloy material industry has a huge capacity, which has a far-reaching impact on resources and the environment, and there is still a long way to go in the development and application of energy-saving, material saving and environmental protection short-process preparation and processing technology.

3. Market demand prospect analysis of China's advanced magnesium alloy material industry

1 High performance rare earth magnesium lightweight structural alloy material

Compared with ordinary magnesium alloy materials, high-performance rare earth magnesium lightweight structural alloy materials have significant advantages such as high strength, good toughness, heat resistance and corrosion resistance after the addition of rare earth, which solves the key problems restricting the wide application of magnesium alloy materials, and is the key basic material to promote the lightweight development of China's aviation, aerospace, automotive, rail transit and other fields. China is rich in magnesium and rare earth resources, mature alloy forming and processing technology, large market application space, rare earth magnesium alloy light structural materials industry system is complete, can achieve self-production and self-marketing.

The future market demand for high-performance rare earth magnesium lightweight structural alloy materials is mainly concentrated in: (1) Development and application of high-performance magnesium rare earth master alloy and rare earth magnesium alloy short process and low cost preparation technology; ② Development of new high-performance rare-earth magnesium alloy materials for application; ③ Advanced processing and forming technology and supporting equipment research and development; (4) Improve the rare earth green smelting and separation technology, and accelerate the promotion and application; ⑤ For the systematic research of material life cycle, the establishment of "industry-university-research and application" collaborative development platform; Accelerate the application of high-performance rare earth magnesium light structural materials, in the next 3 to 5 years to achieve the transformation of the military field to the civilian field, gradually expand the market size, by 2035 will replace the proportion of ordinary magnesium alloy materials to reach 30%.

2 High strength and high thermal conductivity magnesium alloy material

With the continuous development of aviation, aerospace, a new generation of weapons and equipment, high-speed trains and new energy vehicles and other fields, the number and layout density of high-power density electromagnetic devices continue to increase, and the heat generated during operation must be immediately exported, otherwise the temperature is too high will seriously affect the stability and reliability of equipment operation, and greatly shorten the service life of various equipment. Therefore, how to quickly and effectively generate heat in the context of lightweight is an important problem that needs to be solved.

High strength and high thermal conductivity magnesium alloy materials and products production technology is to support the development of aircraft, high-speed trains, automobiles and computers and other advanced basic materials and key technologies, to achieve the above equipment lightweight, improve system stability and service life has an important role, by 2035, will replace the use of similar ordinary high thermal conductivity alloy materials more than 30%. Traditional high thermal conductivity metals, such as Ag and Cu, are difficult to meet practical application requirements due to their high density (about 10.5g/cm3, 8.9g/cm3, respectively) and high price. Magnesium alloy material has the advantage of low density, which is one of the potential material systems to meet the application needs, but the thermal conductivity of commonly used magnesium alloy is still significantly different from that of aluminum alloy. The preparation and processing technology of 125W/(m·K) high strength and high thermal conductivity magnesium alloy materials and their products is the main direction of development in this field.

3 High strength and high conductivity magnesium alloy material

Mobile phones, global positioning system (GPS)/Beidou satellite navigation system and broadband network systems will cause noise due to high-frequency electromagnetic interference, which affects the communication quality, and ordinary laptops are prone to electromagnetic signal leakage during operation, resulting in information or data leakage. In addition, if the human body is exposed to strong electromagnetic fields for a long time or the brain is in close contact with electromagnetic sources for a long time, it may be easy to induce cancer lesions. Therefore, electromagnetic shielding can not only prevent the electromagnetic wave emitted by electronic devices from affecting other devices and the human body, but also protect the electronic devices from interference from other devices. Excellent electromagnetic shielding effect is a necessary and imperative choice for the development of information home appliances. The electromagnetic shielding effect mainly depends on the electrical conductivity of the electromagnetic instrument equipment housing material, the better the electrical conductivity, the better the corresponding electromagnetic shielding effect.

Traditional highly conductive metals such as Ag, Cu, due to the high density and high price, it is difficult to meet the application needs of the field of information home appliances, so the density is lower than aluminum alloy, conductivity greater than the common aluminum alloy cooling materials put forward an urgent demand. Magnesium alloy material has the advantage of low density and is one of the potential material systems to meet the above requirements, but there is a significant gap in the conductivity of commonly used magnesium alloy materials compared with aluminum alloy. Therefore, electrical conductivity; The preparation and processing technology of 17MS/m high-strength and high-conductivity magnesium alloy materials and their products is the main direction of the future development of this field, which plays an important role in reducing the weight of products, improving the safety of system operation, and ensuring the health of related personnel. It is expected that by 2035, the use of high-strength and high-conductivity magnesium alloy materials to replace similar ordinary materials will exceed 25%.

4 Ultra-high strength magnesium alloy material

Ultra-high strength magnesium alloy materials are advanced basic materials that support the continuous upgrading and development of high-end equipment such as aviation, aerospace, new generation weapons and equipment, high-speed trains and new energy vehicles. China is at the forefront of the world in the research and development and application of ultra-high strength deformed magnesium alloys. However, from the perspective of further expanding the application of magnesium alloy materials, the existing high-strength magnesium alloy materials have obvious shortcomings in specific strength, specific stiffness, fracture toughness and performance stability and consistency, which seriously restricts the application of magnesium alloy materials in the above fields and improves the competitiveness of its end products, and is a development problem that needs to be solved. Ultra-high strength magnesium alloy materials and their strengthening and toughening deformation processing technology are the main direction of the development of magnesium alloy field. It is expected that by 2035, ultra-high strength magnesium alloy materials will replace more than 20% of similar ordinary materials.

5 Mg-Al series, Mg-Zn series, ZK series magnesium alloy materials

At present, there are many grades of magnesium alloys, and the alloy series that has been widely used in many fields is Mg-Al alloy, especially AZ91 magnesium alloy which shows stable process, small burn loss, excellent mechanical properties and high strength corrosion resistance at room temperature. In the aspect of deformed magnesium alloys, Mg-Zn alloys are widely used, which show excellent aging strengthening behavior during heat treatment. In this series, from the alloy grade ZM81, it shows better mechanical properties than MG-Al alloy. ZK series alloy is mainly Mg-Zn-Zr series magnesium alloy, which is one of the most widely used deformed magnesium alloys at present, represented by ZK61 magnesium alloy. After high temperature forming cooling and artificial aging treatment, the tensile strength is greater than 300MPa, and it has good plasticity and corrosion resistance, good machinability, and can manufacture large forgings with complex shapes.

6 Light rare earth Mg-RE is magnesium alloy material

China ranks first in the world in rare earth resources reserves, and has advantages in rare earth mining, smelting and separation. However, at present, the application of 16 rare earth elements (except Pm) is unbalanced, and there are problems such as idle and unsalable light rare earths, resulting in a large backlog of rare earths dominated by elements such as La and Ce in China. At present, with the continuous expansion of demand for automotive lightweight, electronic communications and other related industries, major terminal enterprises and material manufacturers have been committed to the research and development of lightweight components, and the performance requirements of magnesium alloy materials have reached an unprecedented height, and even produced many structural and functional integration needs. This has brought new opportunities to the development of rare earth magnesium alloys, especially the development and application of light rare earth magnesium alloys, giving full play to the advantages of rare earths such as La and Ce in magnesium alloys, and the application prospect is very broad.

Compared with Mg-Al and Mg-Zn alloys, the Mg-RE alloy after alloying rare earth elements has more stable process properties during the casting process, and shows better mechanical behavior in mechanical experiments. The application of La and Ce rare earths in magnesium alloys is relatively mature AE series magnesium alloys, which are mainly added in the form of mixed rare earths, typical representatives such as AE44 and AE41 magnesium alloys, which have excellent mechanical properties, especially in the elongation of far more than AZ91, AM60 and other traditional non-rare earth magnesium alloys. The good fluidity of Mg-RE alloy makes it easy to die casting, and the price advantage is obvious, which can meet the large-scale production of civilian products, such as the automotive gearbox housing and other parts. In addition, the solid solubility of light rare earth in Mg is very low, which is conducive to improving the thermal conductivity of magnesium alloy, and has great potential in the future application of electronic products, base stations, access network equipment and other structural parts related to the fifth generation mobile communication technology. The application and development of high-performance light rare earth magnesium alloy materials for the civilian market will help promote the balanced application of rare earth elements, solve the backlog problem of high abundant rare earth elements such as La and Ce, expand the application of rare earth in new fields, accelerate the transformation and upgrading of the rare earth industry, and highlight the strategic value and supporting role of rare earth resources in China's high-tech industry.

7 New superplastic magnesium alloy material

The production cost of the new superplastic magnesium alloy material is relatively low, the profit is high, and the competitive advantage in the production and application of magnesium alloy material is obvious. Previous studies have shown that the new superplastic magnesium alloys developed in China are superior to similar products produced in Japan, and have high room temperature strength (tensile strength > 350MPa, yield strength > 250MPa), strong superplastic deformation ability in the stamping process (medium and low temperature elongation of 100%~200%, high temperature elongation of 700%~800%). It is necessary to further strengthen the research of such materials in the future to provide support for the development of aviation and aerospace technology.

8 New high strength and high plastic casting magnesium alloy material

Cast magnesium alloy has excellent casting performance, machining performance and high specific strength and stiffness, and has been widely used in the aviation and aerospace field in the manufacture of aircraft skin, cabin body, engine parts and other complex structure, large volume thin-walled parts. With the continuous development of aviation, aerospace, automotive, rail transit and other fields, the demand for light complex structure thin-wall parts is strong, so the development of high casting fluidity, excellent strength (tensile strength > 300MPa), high plasticity (elongation > 10%) of new casting magnesium alloy materials are of great significance.

9 Ultralight Mg-Li alloy material

The density of MG-Li alloy is 1.35~1.65g/cm3, with ultra-light and high plasticity characteristics, it is an ultra-light alloy material. The United States has applied Mg-Li alloy to the manufacture of armored conveyor vehicles, non-structural and secondary structural parts in the aviation and aerospace fields. Russia uses MG-Li alloy to make electrical instrumentation parts and shell parts for space vehicles. Japan uses Mg-Li alloy for electronic products housing and sound diaphragm. In recent years, Mg-Li alloy has been used in the manufacture of satellite instrument shell. In the future, with the deepening of research and technological development, ultra-light Mg-Li alloy will have a more in-depth and extensive application in the fields of aviation, aerospace, automobiles, computers, communications and consumer electronics.

10 High performance high temperature resistant magnesium alloy

At present, high performance and high temperature resistant magnesium alloys have been widely used in automobile engine cover, cylinder block, engine piston and high-speed aircraft cabin. At present, most of the research on high performance and high temperature resistant magnesium alloys is focused on the property regulation of Mg, Al and Zn series and the alloying behavior of rare earth elements. Among them, the high temperature mechanical properties are the best Mg-Gd system represented by magnesium rare earth alloy system. At present, it is urgent to solve the problem of improving the strength and plasticity simultaneously, including controlling the shape distribution of precipitated phase, refining the structure and reducing the impurity content. In addition, the casting properties of magnesium alloys should be paid attention to, that is, the mechanical properties and casting properties should be considered comprehensively when the alloy is designed. In terms of performance indicators, ultra-high strength (strength > 400MPa) Heat resistant (service temperature > 250℃) magnesium alloy is a kind of key material that the country needs to tackle urgently. With the continuous development and development of technology, high performance and high temperature resistant magnesium alloys will be widely used in automotive power system components, aerospace vehicles and other areas that have harsh requirements for material strength, high temperature resistance and lightweight materials.

11 New magnesium matrix composites with high performance

The general magnesium alloy material has some problems such as low absolute strength, low stiffness, poor wear resistance and creep resistance, which limit its application in some structural parts and high temperature environment, and can be effectively solved by adding reinforcement such as particles, whiskers or fibers. In addition, the properties of magnesium matrix composites can be effectively controlled by the use of reinforcement type, shape, size and content to meet the application requirements. At present, magnesium matrix composites are mostly prepared by powder metallurgy method of small size components, and the high quality and efficient preparation of large size magnesium matrix composites is an urgent problem for the industry to solve.
