An 8 K elastocaloric temperature change induced by 1.3% transformation strain in Ni44Mn45 − xSn11Cux alloys

(a) Steady stress-strain curves cycled for seven times in Ni44Mn41Sn11Cu4 at a low strain rate of 0.03% s− 1. (b) Near adiabatic stress-strain curve of Ni44Mn41Sn11Cu4 at a high strain rate of 3% s− 1. (c) Corresponding temperature evolutions of specimen surface in-situ measured by an infrared camera during adiabatic compression test in (b). (d) Local temperature-time profile of the central position of specimen (white circle), as well as the average temperature-time profile of the entire detected surface extracted from (c).236
