OS0913 Effect of Alloy composition on phase transformation temperature of Zr-Cu system shape memory alloy
Details
In this study, effect of alloy composition on martensitic and reverse martensitic transformation temperature of Zr-Cu system shape memory alloys were investigated. First, Equiatomic Zr-Cu binary alloy and Zr-Cu-Al ternary alloy were fabricated. The microstructure and phase transformation temperature of these alloys were investigated by XRD and DSC, respectively. Also, compressive test was performed by using Zr-Cu-Al alloy in order to investigate the mechanical properties and shape memory behavior. As the results, it was found that Zr-Cu system alloys have considerable promise as high temperature shape memory alloy. Furthermore, DSC measurement results suggest that the phase transformation temperature of Zr-Cu system alloys decrease with replacement of Cu by Al.
