and the intragranular components of the internal stress caused by the transition of slip mode induces the cyclic hardening and softening at high strain levels. The intergranular internal stress represents the most part...Correlation between the Cyclic Stress Behavior and Microstructure in 316LN based on the Analysis of Hysteresis Loops常波,张峥School of Materials Science and Engineering, Beihang University摘 要:
effect in compression during loading and the detwinning effect during unloading, the alloy showed an asymmetric hysteresis loop. The cyclic stress response exhibited cyclic hardening at high total... more difficult to occur, resulting in cyclic hardening[20-21]. Thus, the cyclic tensile stress in the 2nd cycle is higher than that at the 1st cycle. Fig.2(a) shows the microstructure before fatigue......
