Alloy industry

Scandium, in its elemental form, has been widely used in the doping of aluminum alloys. As long as a few thousandths of scandium is added to the aluminum, a new phase of AI3Sc will be generated, which has a metamorphic effect on the aluminum alloy, and the structure and properties of the alloy have significant changes. Adding 0.2% to 0.4% Sc(this proportion is really similar to the proportion of salt in home cooking, only a little) can increase the recrystallization temperature of the alloy by 150 to 200 ° C, and the high temperature strength, structural stability, welding performance and corrosion resistance are significantly improved, and can avoid the embrittlement phenomenon that is easy to produce when working at high temperatures for a long time. High-strength and high-toughness aluminum alloy, new high-strength corrosion-resistant weldable aluminum alloy, new high-temperature aluminum alloy, high-strength neutron irradiation resistant aluminum alloy, etc., have very attractive development prospects in aerospace, aviation, ships, nuclear reactors, light vehicles and high-speed trains.
