| 摘 要： | 研究了预应变量、加热和冷却工艺对FeMn－Si-Cr－Ni－C形状记忆合金回复应力的影响。结果表明，当预应变量小于3％～4％时，随应变量的增加，回复应力增加。大于3％～4％后，则下降。同一温度下，冷却过程的回复应力大于加热过程的回复应力。停止加热时的温度越高，冷却过程中的回复应力越大。

| Abstract: | The effect of the pre-strain and technique of heating and cooing on the recovery stress of Fe-Mn-Si-CrNi-C shape memory alloy has been studied. The results show that the recovery stress increases with increasing of thepre-strain when it is less than 3% ~ 4%. It is the opposite when prestrain is higher that 3% ~ 4%. At the sametemperature, the recovery stress in the cooling process is greater than that in the heating process. The higher the temperature of cooling is, the greater the recovery stress is. |
