摘要
Abstract
Influence of annealing on the microstructure and mechanical properties of the Al-Mn-Mg alloy was studied by mechanical properties test, OM and TEM observation. The results show that after annealed below 300℃, alloy happens only with recovery, and annealed at 300-400℃, the recrystallization happens now. A large amount of manganiferous particles precipitate during annealing at 400℃, which play the role of dispersion-strengthened. After annealed at 400℃ for 1h, alloy has fine equiaxial grain structure with full recrystallization and also posses better mechanical properties.关键词
