摘　　要：利用正电子湮没寿命谱研究了几种不同成分Ｆｅ基形状记忆合金预应变过程中缺陷结构的变化。The positron annihilation lifetime spectra was employed to investigate the variation of defect structure in several Fe based shape memory alloy with various compositions. The influence of this variation on the shape memory effect of alloys was discussed.
