【Abstract】 The melting process and heat treatment cycle of the cast aluminum alloy containing element Scandium were determined. The composition and microstructure were investigated. Mechanical properties were tested. The results showed that the reasonable processes of melting and heat treatment are suitable for the aluminum alloy containing element scandium, and can obtain higher comprehensive mechanical properties, which exceed the specifications by 2A16 standard.更多还原
