Abstract

Abstract: Solution treatment of 20% Al-Li alloy in an electric field has been studied. The results show that it increases the solubility of elements and accelerates the nucleation of T1-phase and promotes the formation of the precipitation free zones(PFZ), and increases the strength and decreases the plasticity of the alloy.

Key words: 2091 Al-Li alloy, solution treatment, electric field treatment, strength, plasticity
