中文摘要: 利用WDW-10微机控制电子式万能拉伸试验机和D/max2500PC全自动X射线衍射仪研究TiNiCr形状记忆合金的超弹性。结果表明，试样的超弹性受热处理影响显著，不同温度下热处理的样品呈现出不同的弹性曲线。随着加热温度和保温时间的增加，样品弹性先增强后减弱。TiNiCr合金在430℃的退火温度下，保温10~20min可以呈现出良好的完全非线性超弹性。经过热处理的试样会析出强化相Cr3Ni2，析出在430℃保温20min时达到极值，之后随着温度的增加和保温时间的增长都会降低。在该热处理工艺下产生的样品超弹性达到极值。
Abstract:The super-elastic performance of TiNiCr shape memory alloy is investigated by using the WDW-10 Electronic Universal testing machines and XRD test. The results show that the super-elastic performance of the sample is remarkably influenced by the heat-treatment technology, and the elastic curves are different for the samples heat-treated with different temperatures. With the increase of heat-treatment temperature and retention time, the elastic property is firstly increased and then decreased. The completely super-elastic performance of the TiNiCr alloy can be achieved by heat-treatment at 430℃ for 10~20min. The strengthening phase Cr3Ni2 may be formed in the heat-treatment process, the quantity is the maximum of at 430℃ for 10~20min, then is reduced with the increase of the heat-treatment temperature and retention time. The best super-elastic performance is achieved at this case.
