Continuous cooling transformation diagrams are determined for microalloyed steels containing Ti, Nb, Mn and Mo in undeformed as well as in thermomechanically processed conditions using dilatometry. Effects of thermomechanical processing, cooling rate and Nb content on γ/α transformation kinetics are presented. Thermomechanical processing is found to accelerate the onset of γ/α transformation (γ transformation start temperature, Ar<SUB>3</SUB>, is raised). However, the progress of γ/α transformation is retarded considerably in deformed samples. Increase in cooling rate lowers Ar<SUB>3</SUB> significantly and accelerates the progress of transformation. Nb lowers Ar<SUB>3</SUB> undeformed austenite but raises Ar<SUB>3</SUB> of thermomechanically processed austenite.
