A theory is developed for the quantitative representation of the strain induced transformation of retained austenite in low alloy, TRIP-assisted steels of the type developed for the automobile industry. It is possible, therefore, to calculate the fraction of austenite as a function of the plastic strain, chemical composition, deformation temperature and the starting amount of austenite. The effect of composition and temperature is expressed through the free energy available for transformation. Good agreement has been obtained with published experimental data. The model can be used to investigate the stability of the austenite during plastic deformation.

- Steels for bearings (2012, background): “The austenite in such bearing steels is in contrast to the much higher carbon retained austenite found in association with bainite in silicon–containing steels where it is in fact the hardest phase in the structure [203] and hence is much more stable during plastic deformation [204].”
