Abstract
The effect of deformation induced martensite transformation on the mechanical properties in austenitic stainless steel with high Mn was studied. ${\alpha}$'-martensite was formed by deformation in austenitic stainless steel with high Mn. Deformation induced ${\alpha}$'-martensite was formed with surface relief by cold rolling. With the increase of deformation degree, volume fraction of deformation induced martensite was increased rapidly in early stage of deformation and then, increased slowly. With the increase of deformation degree, hardness and tensile strength were rapidly increased with linear relations, while elongation was rapidly decreased and then slowly decreased. Hardness, tensile strengths and elongation were influenced strongly by deformation induced martensite.
