The temperature dependence of elastocaloric cooling properties of a NiTi alloy with a grain size gradient, which was obtained by cold rolling and subsequent laser surface annealing, was evaluated and compared with those of coarse-grained and as-rolled NiTi. Results show that the adiabatic temperatur...
