在Fe-31.2Pd（at. %）单晶。由绝热应力的去除引起的温度降低约为2K，并且在100 MPa的应力下计算出制冷能力为2 MJ/m3。在很宽的温度范围内，这种显着的弹性热效应是由显着的温度依赖性的杨氏模量在[001]P方向。
A significant elastocaloric effect was detected in a Fe-31.2Pd (at. %) single crystal when a compressive stress was applied in the [001]P direction of the parent phase at temperatures of 240-290 K. The temperature decrease caused by the removal of adiabatic stress was approximately 2 K and the refrigeration capacity was calculated to be 2 MJ/m3 under a stress of 100 MPa. This significant elastocaloric effect over a wide temperature range was caused by the remarkable temperature dependence of the Young's modulus in the [001]P direction.
