Martensitic transformations are solid-state transformations on completion of which a hard phase having very high dislocation density is obtained. Despite often being an unfavourable phase because of its typical hard and brittle nature, martensitic transformations have been exploited in designing of Transformation Induced-Plasticity (TRIP) steels as first explained by Zackay et al. In alloys such as TRIP steels, and other steels where the martensite start temperature is below room temperature, martensite transformation can be initiated by the application of a mechanical driving force or external stress. The aim of the present proposal is to characterise and determine the influence of the different transformation regimes on the proceeding work hardening rate combining EBSD, DIC and neutron diffraction measurements on the same sample.
