【Abstract】 Scandium is the most effective alloying element to optimize the property of aluminium alloys. The mechanism of effects of scandium element on ultra high strength aluminium alloys are fining cast microstructure, inhibiting recrystallization, enhancing mechanical property, improving welding property and stress-corrosion resistance. Based on domestic and overseas research on aluminium alloys contained scandium, the paper puts some suggestions for the future exporation of ultra high strength aluminium alloys.更多还原
