Abstract
A difference in fatigue strength depending on the rotational speed between air and water was found for the rotating-bending fatigue characteristics of a TiNi shape memory alloy wire in our previous work. The heat transfer cha racteristics around a shape-memory alloy wire were measured using Reynold's analogy. The rise in temperature of the metal during the rotating-bending cycles was calculated considering the heat transfer result. As a result, th e rotating-bending fatigue characteristics of a shape-memory alloy wire wer e explained well from the viewpoint uf the heal transfer characteristics.
