on September 21,China’s leading special light alloy manufacturer ZZQY Light Alloy Material Technology Group
released a new type of high-strength heat-resistant magnesium rare-earth alloy material: high-strength, large-width magnesium-rare-earth alloy sheet with excellent weldability and industrialized mass production. The tensile strength of the new-type magnesium-rare-earth alloy rolled sheet can reach 365MPa. The yield strength is 310MPa, and the elongation is greater than 6%.
With the continuous growth of the national defense industry’s demand for lightweight, high-performance land unmanned armored vehicles, airdrop light armored vehicles and other new military weapons have more and more urgent needs for lightweight structural materials and armor. Magnesium alloys are a kind of lightweight, High-strength structural materials are easier to achieve mass production and become one of the preferred alternative materials.
Magnesium rare earth alloys are being studied and applied more and more widely due to their low density, high strength, corrosion resistance, excellent high temperature resistance and weldability. In aerospace, it can be used as missile cabin and cabin material and other secondary load-bearing parts that require high temperature resistance; in medicine, it can also be used as a biomedical human implant material; in addition, this alloy is also being studied Used in composite helmet shells, its light weight, high specific stiffness, high damping and proper ballistic resistance may cause performance improvements. The United States’ Fuel Efficient Ground Vehicle Demonstrator (FED) program is also using such alloys to design tactical vehicles to reduce fuel consumption in the theater, and its fuel economy is significantly higher than other land armored vehicles. The idea of ”lighter, more mobile, and more flexible” army construction has become the mainstream.
In the future, the army will deal with more and more rapid and mobile operations and low-intensity operations such as urban operations, counter-terrorism, anti-riot operations, and peacekeeping operations. Wheeled armored combat vehicles with faster response and deployment speeds will surely play a pivotal role. This powerful traction force that “shapes the new army” fundamentally determines the development trend of wheeled armored combat vehicles.
ZZQY has developed a higher-strength magnesium rare earth rolled sheet, which optimizes its strength at the expense of partial plasticity (tensile strength greater than 400MPa, yield strength greater than 300MPa, and elongation greater than 4%).
