摘　　要：在阐述铸锻复合成形工艺及其发展现状的基础上,提出了AZ91D镁合金凝固后直接形变这一新思路。通过试验,初步对AZ91D镁合金凝固后直接形变的显微组织进行了研究。结果表明:采用凝固后直接塑性变形未出现缺陷,变形区域晶粒变得更加细小,有了明显的流线。Based on the forging compound forming process and its development status, AZ91D alloy during direct deformation after solidification process was researched. The microstructure of the alloy during direct deformation after solidification was studied. The results show that： the plastic deformation directly after solidification generates no defects. The microstructure of grain in deformation zone become finer, which show a significant flow line.
