An investigation was conducted to examine the low cycle symmetric push-pull fatigue behaviour of the Cr-Mn-N dual-phase stainless steel.Two groups of specimens,A and B, were used,they were solution treated at 1050 and 1250℃,respectively.The.fatigue life of group A is almost twice as long as that of group B under the same total strain amplitude.The energy loss during the fatigue tests and the mophology of the fracture surfaces have been stu- died and discussed. 展开更多
