The Use Of Aluminum Alloys

The Use of Aluminum Alloys
Adding a small amount of scandium to aluminum alloys can promote grain refinement and increase the recrystallization temperature from 250 ° C to 280 ° C. It is a powerful grain refiner and an effective inhibitor of aluminum alloy recrystallization. It has a significant impact on performance, including strength, hardness, welding performance, corrosion resistance, etc. All have been greatly improved. Scandium has a good dispersion strengthening effect on aluminum and maintains a stable non recrystallization structure under hot working or annealing conditions. Some alloys are cold-rolled sheets with significant deformation, which maintain this structure even after annealing. The inhibition of scandium on recrystallization can eliminate the recrystallization structure in the weld Heat-affected zone. The sub crystalline structure of the matrix can directly transition to the casting structure of the weld seam, resulting in high strength and resistance of the welded joints of scandium containing aluminum alloys. Corrosion performance. The effect of scandium on the corrosion resistance of aluminum alloys is also due to its refinement of grain size and inhibition of recrystallization process. The addition of scandium can also improve the superplasticity of aluminum alloys, and the elongation of aluminum alloys with about 0.5% scandium can reach 1100% after superplastic treatment. Therefore, aluminum scandium alloy is expected to become a new generation of lightweight structural materials in industries such as aerospace, aviation, and shipbuilding. Russia has developed over 10 brands of scandium containing aluminum alloys, mainly used for welding loads in aerospace and ships. Structural components and aluminum alloy pipes in alkaline corrosive media environments, railway fuel tanks, key structural components of high-speed trains, etc
