研究了三种不同成分的铁锰硅形状记忆合金。结果表明，合金Ｆｅ－１４Ｍｎ－６Ｓｉ－９Ｃｒ－５Ｎｉ具有较好的形状记忆效应。经训练后，在预变形为４％～９％范围内，相对应变回复率可提高４０％左右，绝对应变回复率可达６．２％。
Three different compositions of ferromanganese silicon shape memory alloy were studied. The results show that the alloy Fe-14Mn-6Si-9Cr-5Ni has good shape memory effect. After training, in the range of 4% ~ 9% of the pre-deformation, the relative strain recovery rate can be increased by about 40%, and the absolute strain recovery rate can reach 6.2%.
