Abstract
Comparison of the plastic flow properties of transforming metastable austenite, stable austenite, and martensite over a range of temperatures and strain rates allows quantitative estimates of (a) the static-hardening effect of the two-phase mixture and (b) the dynamic-softening effect of the transformation as a deformation mechanism. A constitutive relation is derived predicting the flow behavior of metastable austenite from the strain-induced transformation kinetics and the flow properties of the two separate phases.
