Abstract: The microstructure especially the lamellar second phase evolution by a combination of deformation and heat treatment for AZ80 alloy was investigated. The results show that there are finer lamellar Mg₁₇Al₁₂ phases after hot compression with the increasing strain, while there are coarse lamellar discontinuous precipitation cells of β-Mg₁₇Al₁₂ phase spreading from the grain boundaries into the grains after T6 treatment of the compressed samples. The lamellar morphologies especially the lamellar distance of β-Mg₁₇Al₁₂ phase precipitation of the T6 treated deformation specimen at different strains differ from each other as there are different grain boundaries in the corresponding compressed specimens.
