Abstract

A model using energy balance is proposed to describe the volume fraction of martensitic transformations.It is found that in the absence of external stress, the volume fraction of martensite (xi) in the forward austenite-to-martensite transformation is proportional to the undercooling and inversely proportional to a linear function of the instantaneous temperature T. Similarly, for the reverse transformation from martensite to austenite, (xi) is proportional to and inversely proportional to a linear function of T. The results obtained from this model are in good agreement with experimental results.
