英文摘要	The influence of hydrostatic-pressure training on barocaloric effects (BCEs) has been investigated for the Pd59.3In23.2Fe17.5 shape memory alloy. We demonstrate that the shift of the martensitic transformation temperature by the applied pressure (dT(m)/dp) could be significantly improved from 11 K to 21 K GPa(-1) by hydrostatic-pressure training. By using an indirect method of the magnetic measurement under an external pressure to determine the barocaloric effect, the entropy change for the Pd59.3In23.2Fe17.5 alloy increases from 15 to 16 J kg(-1) K-1 after hydrostatic-pressure training. The alloy also exhibits a wider working window and a larger refrigeration capacity (from 113 to 171 J kg(-1)) after pressure training. Moreover, the maximum reversible entropy change Delta S-rev increases from 3 J kg(-1) K-1 to 8 J kg(-1) K-1 and the reversible RC increases from 11 J kg(-1) to 50 J kg(-1) by hydrostatic-pressure training. The hydrostatic-pressure training is a feasible approach to obtain an improved realistic BCE by a lower pressure.
