Cu、Mn对TiNi合金伪弹性的影响
|
摘要
在不同目标载荷条件下对添加了Cu、Mn的TiNi合金进行压缩试验,研究了Cu、Mn元素的添加对其伪弹性的影响。结果表明,Cu元素不利于提高合金的伪弹性,随Cu含量的增加,合金的伪弹性降低;在一定条件下,添加了Cu、Mn两种元素的TiNi合金的伪弹性明显优于TiNi二元合金,但经过一定的压缩循环后,前者的伪弹性会突然变差。
Influence of adding Cu and Mn on the pseudoelasticity of TiNi alloy was investigated by means of compression test under different target loads.The results show that Cu is not conductive to improve the pseudoelasticity of alloy.With increasing Cu content,the pseudoelasticity decrease.Under the certain conditions,the pseudoelasticity of TiNi alloy with Cu and Mn are significantly superior to those of TiNi binary alloy.However,after some compression cycles,the pseudoelasticity of the former decreases suddenly.
