Ti-Ta High Temperature Shape Memory Alloys
IOP Conference Series: Materials Science and Engineering, 2018 The actuation based on shape memory alloys relies on the martensitic phase transformation that allows the reversible transition from the "soft" martensite phase to the "hard" austenite phase. Usual shape memory alloys usually have transformation temperatures around room temperature.
