主 题:carburized steel fatigue microhardness
摘 要:The fatigue behavior of quenched plus tempered carburized steel before crack initiation has been observed in tension-tension fatigue *** was found that fatigue softening and fatigue hardening coexist in this steel.A transition region near the ease depth of the steel divides the cross section of a round speeimen into two parts:the softened part outwards and the hardened part *** degree of fatigue softening in the case and fatigue hardening in the core is increased with the maximum applied cyclic stress and the number of cycles.
