Influence factors on evolution of structure in hot rolled TRIP steels during TMP(Thermnomechanical processing)finishing rolling(austenite deformed in non-crystallization region)
ROT(run out table)cooling(phase transformation in y-a two phase region)and coiling process (bainite transformation);evolution of structure of cold rolled TRIP steel during intercrilical annealing(γ-a region)and bainite isothermal region transformation
and carbon enrichment in retained austenite of TRIP steel during structural evolution are presented.
