Abstract
A formula to describe the creep strain-rate based on the random barriers theory was presented by considering the process in which the movable dislocations could surmount the barriers in the field of resisting force with the help of thermal fluctuations. An effect of loading strain-rate on the stress-strain curves in cyclic loading at a slow rate was discussed with a new equation combined by the above formula and the equilibrium equation between the stress-rate and the strain-rate at any stress which had been derived in the previous paper. The results simulated by the above new equation show that the hysteresis curve at room temperature may shift conspicuously to the lower stress level as the loading strain-rate comes near to the creep strain-rate.
