TRIP-Assisted Steels: Stress or Strain-Affected Martensitic Transformation

S. Chatterjee and H. K. D. H. Bhadeshia

Abstract

Transformation induced plasticity (TRIP) assisted steels contain a small quantity of carbon enriched retained austenite, which transforms into martensite during the course of plastic deformation. Transformation of this kind can be induced by both stress and plastic strain. The detailed mechanism by which the martensite is induced is different for these two scenarios. An attempt is made here to discover the relative importance of these mechanisms and it is found that stress-affected transformation can explain much of the variation in retained austenite content as a function of plastic strain.
