heat-treated counterpart at different temperatures. The experimental results show that the ultimate tensile strengths of two alloys decrease very slowly with increasing temperature up to 200?C... failure was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It shows that cyclic slip combined with environmental effect may be the main crack initiation......
