| Abstract: | This peper investigates the influence of strain amplitude, temperature andalloy elements on the low cyclic fatigue (LCF) characteristics of 40Cr-30Ni series and 25Cr-20Ni series of austenitic stainless steels. Thearrangements of dislocation of the experimental alloys in LCF are observedwith TEM, and the hardening and softening mechanisms of the materialsare discussed. |
