| 摘 要： | An investigation was conducted to examine the low cycle symmetric push-pull fatiguebehaviour 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 ofgroup A is almost twice as long as that of group B under the same total strain amplitude.Theenergy loss during the fatigue tests and the mophology of the fracture surfaces have been stu-died and discussed.
