Characteristics of deformation-induced transformation (DIT) in the refractory low alloy steel 2.25Cr1Mo were experimentally studied. Effect of different controlled-rolling and controlled-cooling process on the steel microstructure and mechanical properties were investigated and the mechanism was discussed. Results show that the grain size and the ferrite volume fraction were obviously affected by the rolling and cooling processes. Proper DIT technique may significantly accelerate the transformation of austenite to ferrite in the steel and improve the steel strength.
