【摘要】 附加弯曲载荷使马氏体逆转变过程中近等原子TiNi合金试样形状恢复被推迟。并且,随载荷增加(直至1831g)形变温度迅速增加。在载荷由0到100g时,相变温度A_s和A_r稍有推迟,进一步增加载荷相变温度保持不变。可以设想形变和相变温度均与界面运动密切相关,但与形变有关的界面运动不完全等同于与相变有关的界面运动。因此,形变温度的推迟并非是相变温发升高所决定的。更多还原

【Abstract】 It is shown that applied load retards the shape recovery temperature of Ti-Ni alloy and the recovery temperature rapidly increases with the increasing of the load. When the load is greater than 100g, phase transformationtemperature does not further change with the increasing of the load. It is propoted that both temperatures are dependent upen the motion of the interfaces, the relations, howerer, are not equal.更多还原
