摘　　要：变形镁合金受限于成形工艺,致使其室温成形性较差并且具有较强的各向异性。通过在不同变形条件进行预变形结合退火处理能够有效弱化镁合金织构从而改善镁合金的力学性能。总结并评述了3种预变形方式结合退火处理对镁合金微观组织与力学性能的影响,并对未来的发展提出了建议。Deformed magnesium alloy is limited by metal forming process,resulting in poor formability at room temperature and strong anisotropy.By pre-deformation combined with annealing under different deformation conditions,the texture of magnesium alloy can be weakened effectively and the mechanical properties of magnesium alloy can be improved.The effects of three pre-deformation methods combined with annealing on microstructure and mechanical properties of magnesium alloys were reviewed,and future tendency was pointed out.
