为了分析形变处理对Ti-18Zr-11Nb-3SN合金的超弹性、相变行为和弹热性能的影响，对几种冷轧钢板在923~1173K温度范围内进行了退火处理，随着退火温度的升高，样品中析出的Zr5Sn3相逐渐溶解直至完全消失。所有样品都经历了应变玻璃行为，随着热处理温度的升高，理想的冻结温度T0从371.3 K逐渐降低到195.3 K。此外，通过调整退火温度，可以将超弹性和弹性热工作窗口展宽到110K。在Elsevier B.V.发表的绝热温度变化为2.5K(C)2022的情况下，获得了样品的弹性热学性能。
To analyze the effect of thermomechanical treatment on the superelasticity, phase transition behavior and elastocaloric properties of Ti-18Zr-11 Nb-3Sn alloys, several cold-rolled sheets were annealed at temperatures between 923 K and 1173 K. With increasing annealing temperature, the precipitated Zr5Sn3 phase in the samples gradually dissolves until it completely disappears. All samples undergo strain glass behavior, and the ideal freezing temperature T0 gradually decreases from 371.3 K to 195.3 K with increasing annealing temperature. Moreover, the superelasticity and elastocaloric working window can be widened to 110 K by adjusting the annealing temperature. The elastocaloric properties of the sample were obtained with an adiabatic temperature change of 2.5 K. (C) 2022 Published by Elsevier B.V.
