介绍了延展性 Cu-Al-Mn 基形状记忆合金 (SMA) 的最新进展。通过热机械处理控制晶粒尺寸和织构，可以增强超弹性（SE）、形状记忆效应（SME）、双向记忆效应（TWME）和内摩擦等各种性能。研究还表明，通过冷轧 Cu-Al-Mn SMA 来控制应力诱发的马氏体转变，可实现低热膨胀 (LTE)。此外，还介绍了 Cu-Al-Mn 基 SMA 导丝的医学应用。
Recent progress on ductile Cu–Al–Mn-based shape memory alloys (SMAs) is presented. The various properties of superelasticity (SE), the shape memory effect (SME), the two-way memory effect (TWME) and internal friction are enhanced by controlling grain size and texture through thermomechanical treatments. It is also shown that the control of stress-induced martensitic transformation due to cold-rolling of Cu–Al–Mn SMAs results in low thermal expansion (LTE). In addition, the medical application of the Cu–Al–Mn-based SMAs to guidewire is introduced.
