| 摘 要： | 对NiTi形状记忆合金在冷轧变形后的不完全相变特征进行了研究.通过设计试样原始表面形状的方法,将具有不同位错密度的宏观区域引入形状记忆合金内部,使整个材料获得了复合材料的特征.结果表明,由于位错织构和马氏体变体界面的作用,使逆转变温度扩展到一个较大的温度范围,这将会进一步增加温度记忆效应的潜在应用价值.

| Abstract: | Incomplete martensitic transformation characteristics of NiTi shape memory alloys after cold deforma-tion are studied.By designing the shape of the original surface curve,macroscopic domains with different dislocation density are introduced into the NiTi alloys and materials possessing the characteristics of composites are obtained.Due to the interactions between the dislocation texture and martensite variants,the reverse transformation temperatures are found to expand over a large temperature window,which ... |
