摘　　要：研究将脉冲电场作用于合金的凝固过程,脉冲电场及时效处理对Fe-Mn-Si-Cr-Ni合金显微组织和形状记忆效应的影响,结果表明经脉冲电场处理的试样固溶后时效形状记忆效应最佳,形状回复率最高达到39.8%.The dissertation was focused on imposing pulse electric field in the solidification process of the alloy. The influence of the pulse electric field and aging on the microstructure as well as the shape memory effect on the Fe-Mn-Si-Cr-Ni alloy was researched. The results expatiated that the tested samples dealed with the pulse electric field, aging after solution treatment had achieved the best shape memory effect, the highest shape memory recovery was 39.8%.
