Identical Area Observations of Deformation-Induced Martensitic Transformation in SUS304 Austenitic Stainless Steel

Abstract: In this study, an identical area of a SUS304 austenitic stainless steel specimen was observed by electron backscattering diffraction measurements at different strains in tensile test at ambient temperature, in order to investigate the details of deformation-induced martensitic transformation. Firstly, a number of thin deformation twins were formed in austenite grains. Most of the martensite crystals were observed either near grain boundary triple junctions or inside the deformation twins. Secondly, it was foun… Show more

“…[44,45] In many Metastable Austenitic Stainless Steels (MASS), martensite can also be found in curved twins without the need for an intersection with another twin. [46][47][48] MASS are an older class of steels which have been extensively studied. They share a large number of similarities with medium Mn steels such as the TWIP + TRIP effect and are therefore a very useful guide to the understanding of medium Mn steels.…”

“…But if the twins were kinked then it might be possible that the deformation may have provided a suitable secondary shear to nucleate martensite within the twin [43,44]. In many Metastable Austenitic Stainless Steels (MASS), martensite can also be found in curved twins without the need for an intersection with another twin [45][46][47]. MASS are an older class of steels which have been extensively studied.…”
