对TiNi形状记忆合金丝的旋转弯曲疲劳进行了研究。讨论了空气和水的气氛、温度、应变幅值和转速对疲劳寿命的影响。当应变幅值为菱形相变时，疲劳寿命延长10(7)次以上。当应变幅值为马氏体相变时，合金在空气中的疲劳寿命小于在水中的疲劳寿命。1997爱思唯尔科学有限公司
The rotating-bending fatigue of a TiNi shape-memory alloy wire was investigated. The influence of air and water atmospheres, temperature, strain amplitude and rotational speed on the fatigue life was discussed. In the case of the strain amplitude due to the rhombohedral-phase transformation, the fatigue life lengthened above 10(7) cycles. In the case of the strain amplitude due to the martensitic transformation, the fatigue life in air was shorter than that in water. (C) 1997 Elsevier Science Ltd.
