| 摘 要： | 研究了Fe-20．69Mn-4．93Si-8．15Cr-4．86Ni-0．14N合金的形状记忆特性．结果表明：Fe-Mn-Si-Gr—Ni形状记忆合金经过N合金化后，其形状恢复率得到明显的改善．预应变量为6．2％～9．4％时，经适当热处理后其形状恢复率可达到3.6％～4．2％；当预应变量较小时，热机循环训练对合金的形状恢复率影响不大，而当预应变量较大(ε=9．4％)时，二次热机循环训练后合金的形状恢复率最高，三次训练后合金的形状恢复率又开始下降．

| Abstract: | The character of SME in Fe-Mn-Si-Cr-Ni-N alloys has been studied. The resultes show that the racovery of Fe-Mn-Si-Cr-Ni-N alloys have beenimproved after nitrogen alloying. The racovery ratio could get to 3.6% ~ 4.2%, when the pre-strain was 6.2% ~ 9.4%. In addtion, the number of trainning cycles hadly has effect on SME, when the pre- strain was small. While, as the pre-strain get to 9.4%, the racovery ratio get maximum after 2 number trainning, then began to reduce with the number increacing. |
