摘要：
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.
