| 摘 要： | 研究了TiNiMo形状记忆合金的相变特性、形状记忆效应和力学性能,结果表明:TiNiMo合金存在一个R相变,Mo的加入降低了TiNi合金的马氏体相变开始温度（Ms）,Ti50Ni48.5Mo1.5和Ti50Ni48Mo2.0合金的Ms分别达到了-85℃,-103℃,这两种合金分别在8.51%和8.26%的预应变下获得了8.06%和7.71%的形状记忆效应。Ti50Ni48Mo2.0合金的屈服强度和抗拉强度分别为589MPa和799MPa,比Ti50Ni48Fe2.0的相应强度分别高73%和31%,同时Ti50Ni48.5Mo1.5的力学性能也较为优异,因而TiNiMo合金是很有发展潜力的新型的记忆合金接头材料。

| Abstract: | Phase transformation behaviors, shape memory effects and mechanical properties of TiNiMo shape memory alloys are investigated. It is found that a R phase transformation exists in TiNiMo alloy, and the adition of Mo will lower the martensite start （Ms） temperature of TiNi alloy, and that the Ms temperatures of Ti（50）Ni（48.5）,Mo（1.5 ）and Ti（50）Ni（48）Mo（2.0 ）alloys are -85℃ and -103℃, respectively. The two alloys will gain 8.06% and 7.71% shape memory effects under 8.51% and 8.26% pre-strain,... |
