Improvement of damping properties in laser processed superelastic Cu-Al-Mn shape memory alloys

Cu-based shape memory alloys may be a prime candidate to replace NiTi in specific applications due to their reduced cost and excellent superelasticity. Superelastic Cu-Al-Mn alloy is currently being studied for potential applications as damping systems in seismic devices. However, joining techniques are often required to obtain complex shapes to be incorporated into multi-functional systems. In this study, the effect of post-weld laser …
