Abstract
The spatial distribution of martensite laths at different strained austenite grains has been thoroughly investigated by strain rate variation during tensile deformation of metastable austenitic stainless steel at ambient temperature. Deformation induced martensitic transformation has been studied through direct measurement of martensite fraction and their distribution at various levels of stress/strain for different strain rates. The nature of distribution of martensite laths closely corresponds to the local stress-state and strain-state variation in a tensile deformed and fractured specimen. The martensite laths' distribution pattern is strongly attributed to the crystallographic nature of variant selection due to applied stress. It has also been investigated that the spatial distribution of martensite lath is strain rate dependent.
