采用热膨胀法研究了镶嵌在NbTi基体中的TiNi形状记忆合金的约束不完全相变迟滞现象。结果表明，迟滞宽度（一次不完全转变停止温度与随后的恢复转变开始温度之间的温差）非常窄，在测试温度范围不超过前一次温度范围的热循环中，迟滞宽度几乎减小到零。此外，可以在很宽的温度范围内观察到具有如此窄迟滞宽度的转变。(C) 2012年Elsevier B.V.出版
Constrained incomplete transformation hysteresis of TiNi shape memory alloy embedded in NbTi matrix was studied by thermal dilatation. Results showed that hysteresis width (temperature difference between one incomplete transformation arrest temperature and the subsequent reverted transformation starting temperature) was very narrow, and it reduced to almost zero in the thermal cycle where the testing temperature range was not beyond its previous one. Furthermore, transformations which showed such narrow hysteresis width could be observed within a very wide temperature range. (C) 2012 Published by Elsevier B.V.
