我们报告了 Cu-Zn-Al 形状记忆合金的弹热效应。我们表明，等温熵和绝热温度变化都很大，并且在类似于 130 K 的非常宽的温度范围内进行现场循环时可重现。大熵和如此宽的温度范围的结合导致了类似于 2300 J/kg 的出色制冷能力。 (C) 2013 AIP 出版有限责任公司。
We report on the elastocaloric effect in a Cu-Zn-Al shape memory alloy. We show that both the isothermal entropy and adiabatic temperature changes are large and reproducible upon field cycling over a very broad temperature span of similar to 130 K. The combination of large entropy and such a broad temperature span results in an outstanding refrigerant capacity of similar to 2300 J/kg. (C) 2013 AIP Publishing LLC.
