Small stress-hysteresis in a nanocrystalline TiNiCuFe alloy for elastocaloric applications over wide temperature window

Shape memory alloys (SMAs) with small stress-hysteresis and wide superelasticity temperature window are highly desired for elastocaloric applications. In this study, a nanocrystalline Ti50Ni42Cu6Fe2 SMA is fabricated by casting, forging, wire-drawing and annealing. The alloy exhibits superelasticity...
