热机械循环方法对训练NiTi合金双程形状记忆效应的影响 侯文生1,廖彦剑1,牟波1,杨军1,郑小林1,罗洪艳1 (1.重庆大学生物工程学院,重庆,400044) 摘要:采用4种典型的热机械循环方法训练获取具有双程形状记忆效应的镍钛合金丝,从双程形状回复量,高温相形状,低温相形状和相变温度的变化等方面系统研究了训练方法对双程形状记忆效应训练效果的影响.结果表明,在不同训练方法中镍钛合金丝被加载应变时所处的物质相态的差异是造成不同训练效果的主要原因,其中在马氏体相变过程中因加栽引入的位错最有利于双程形状记忆效应的形成. 关键词:NiTi合金; 热机械循环训练方法; 双程形状记忆效应; [全文内容正在添加中] ......
