Comparison of high temperature shape memory behaviour for ZrCu-based, Ti-Ni-Zr and Ti-Ni-Hf alloys

Comparison of high temperature shape memory behaviour for ZrCu-based, Ti-Ni-Zr and Ti-Ni-Hf alloys

New ZrCu-based high temperature shape memory alloys with M-s close to 500 K are under development. The shape memory behaviour of this material is compared to those of Ti-Ni-Zr and Ti-Ni-Hf alloys. The optimal compositions show a shape recovery of not less than 3% at temperatures above 470 K. (C) 200...

Zusammenfassung:New ZrCu-based high temperature shape memory alloys with M-s close to 500 K are under development. The shape memory behaviour of this material is compared to those of Ti-Ni-Zr and Ti-Ni-Hf alloys. The optimal compositions show a shape recovery of not less than 3% at temperatures above 470 K.
