A phenomenological mechanism of transformation plasticity, or TP, is discussed, in the first part of the paper, to identify the characteristics of mechanical behavior of material. This is based on an assumption that the TP strain it is also a kind of plastic strain, a unified plastic flow theory is derived by introducing the effect of progressing new phase into the yield function of stress, temperature and plasticity related parameters. Thus obtained strain rate reveals to include the transformation plastic part in addition to mechanical and thermal plastic components. Applying the (2) formulated constitutive law with data of TP coefficient K identified, simulation of several cases of coupled metallo-thermo-mechanical processes by use of developed simulation code COSMAP. Special attention is paid on the effect of transformation plasticity to demonstrate that the effect makes a drastic influence for proper numerical simulation results. © 2011 Published by Elsevier Ltd.
