Ni-Mn-In Heusler合金是由于结构转变和磁转变的耦合作用而具有较大弹性热效应和磁热效应的典型体系，这为通过耦合外部机械应力和磁场来改善制冷剂性能提供了一种途径。本文研究了（Ni52Mn31In17-xCux）B0.2 （x = 0,1,2,3）合金的相组成、马氏体相变行为、力学性能和弹热效应。结果表明，（Ni52Mn31In16Cu1）B0.2多晶在220 MPa的低应力下表现出−9.5 K的大绝热冷却，|ΔTad的卸载|/σ值约为43.2 K/GPa。这是所有已报道的Ni-Mn-In Heusler合金中显著的|ΔTad卸载|/σ。在3%的高应变下，经过100次循环后- 6.8 K的ΔTad卸载，它也保持了良好的功能稳定性，这表明它是一种有希望的具有优异综合性能的弹性热制冷材料。Ni-Mn-In Heusler合金是由于结构转变和磁转变的耦合作用而具有较大弹性热效应和磁热效应的典型体系，这为通过耦合外部机械应力和磁场来改善制冷剂性能提供了一种途径。本文研究了（Ni52Mn31In17-xCux）B0.2 （x = 0,1,2,3）合金的相组成、马氏体相变行为、力学性能和弹热效应。结果表明，（Ni52Mn31In16Cu1）B0.2多晶在220 MPa的低应力下表现出−9.5 K的大绝热冷却，|ΔTad的卸载|/σ值约为43.2 K/GPa。这是所有已报道的Ni-Mn-In Heusler合金中显著的|ΔTad卸载|/σ。在3%的高应变下，经过100次循环后- 6.8 K的ΔTad卸载，它也保持了良好的功能稳定性，这表明它是一种有希望的具有优异综合性能的弹性热制冷材料。
A Ni-Mn-In Heusler alloy is a typical system with large elastocaloric and magnetocaloric effects due to the coupling of structural transformation and magnetic transition, which provides a way to improve the refrigerant performance by coupling the external mechanical stress and magnetic field. Here, we investigate the phase constitution, martensitic transformation behavior, mechanical properties, and elastocaloric effect in (Ni52Mn31In17-xCux)B0.2 (x = 0, 1, 2, 3)alloys. It is found that the (Ni52Mn31In16Cu1)B0.2 polycrystal exhibits a giant adiabatic cooling of −9.5 K at a low stress of 220 MPa which has a large value of |ΔTad unloading|/σ about 43.2 K/GPa. This is a remarkable |ΔTad unloading|/σ obtained among all the reported Ni-Mn-In Heusler alloys. It also maintains a good functional stability with the ΔTad unloading of −6.8 K after 100 cycles at a high strain of 3%, indicating that it is a promising candidate for an elastocaloric refrigeration material with excellent comprehensive properties.A Ni-Mn-In Heusler alloy is a typical system with large elastocaloric and magnetocaloric effects due to the coupling of structural transformation and magnetic transition, which provides a way to improve the refrigerant performance by coupling the external mechanical stress and magnetic field.
