【Abstract】 The resistivity and the residual stress of thermal bimetal 5J20110 and its components as a function of stability thermal cycling times were investigated by means of the resistance and X-ray diffraction methods. The results show that,after the first stability thermal cycling,the decrease of residual stress in 5J20110 was the largest, which was the same as the dependence of resistivity on stability thermal cycling times. The effect of stability thermal cycling treatment can be evaluated through the analysis of resistivity.更多还原
