Ｆｅ Ｍｎ Ｓｉ铁基形状记忆合金由于具有优良的加工性而且价格低廉 ,因而受到了广泛关注。含Ｍｎ2 8%～34%和Ｓｉ4 %～ 6 5%的Ｆｅ Ｍｎ Ｓｉ合金具有相当好的形状记忆效应 ,如果添加适量的Ｃｒ和Ｎｉ还能进一步改善其形状记忆效应和耐蚀性。这类合金不同于ＴｉＮｉ和Ｃｕ基?
Fe Mn Si iron-based shape memory alloys have attracted much attention due to their excellent workability and low cost. Fe Mn Si alloys containing 8% ~ 34% Mn 2 and 4% ~ 65% Si 4 ~ 4 have good shape memory effect, and the shape memory effect and corrosion resistance can be further improved by adding appropriate amounts of Cr and Ni. This type of alloy is different from TiNi and Cu-based?
