Effect of deformation and heat treatment on microstructure and mechanical properties of Mg-8Li-1Al-0.6Ce alloy

Abstract

Microstructure and mechanical properties of as-cast, as-rolled and as-annealed Mg-8Li-1Al-0.6Ce alloys are studied. The as-cast, as-rolled and as-annealed Mg-8Li-1Al-0.6Ce alloys are composed of α phase (white), β phase (gray), and AlCe phase. The grains are refined when Mg-8Li-1Al-0.6Ce alloy is rolled. The recrystallization of the as-rolled Mg-8Li-1Al-0.6Ce alloy may take place after the annealing procedure. The results of tensile tests show that the as-annealed Mg-8Li-1Al-0.6Ce alloy possesses peak strength and elongation 233.9 MPa and 24.9 %, respectively.
