Stress-Assisted Isothermal Martensitic Transformation and Transformation Plasticity.

reportActive / Technical Report | Accession Number: ADA073433 | Open PDF

Abstract:

Low-temperature plastic flow in TRIP steels has been found to be controlled by stress-assisted isothermal martensitic transformation. Under these conditions, theory of the transformation kinetics can be used to predict the temperature dependence of the flow stress, the shape of the stress-strain curve, and the dependence of flow properties on stress state.
