摘要：

The martensite to austenite reversion behavior of 90% cold rolled AISI 301 stainless steel was investigated in order to refine the grain size. Cold rolled specimens were annealed at 600-900 degrees C, and subsequently characterized by scanning electron microscopy, X-ray diffraction, Feritscope, and hardness measurements. The effects of annealing parameters on the formation of fully-austenitic nano/submicron grained structure and the mechanisms involved were studied. it was found that annealing at 800 degrees C for 10 s exhibited the smallest average austenite grain size of 240 +/- 60 nm with an almost fully-austenitic structure.
