摘要
研究了冷拔量、热处理工艺参数对Ti49.8%Ni合金丝材的超弹性的影响。结果表明不同冷拔量、不同退火工艺处理的丝材获得完全超弹性的温度区间、超弹性特性都不相同,获得最大超弹性应变量的处理工艺为冷拔量39%、退火温度723K、保温时间30min。
Influence of cold drawing and annealing treatments upon pseudoelasticity of NiTi wire with 49.8% Ni has been examined. It was shown that complete pseudoelasticity and different pseudoelastic characteristics were observed over a temperature range up to 45 K under varying cold drawing and annealing conditions. Excellent pseudoelasticity can be obtained in Ti 49.8%Ni wire annealed at 723 K for 30 min after 39% cold drawing reduction.
