Quantitative analysis of the recrystallized textures of cold-rolled 430 stainless steel during high-temperature annealing

Variations in the recrystallized texture and microstructure of cold-rolled 430 stainless steel during isothermal annealing were investigated on a Gleeble-1500 thermal-mechanic simulator at 750, 800, 825 and 850℃, and the evolution of main textures was analyzed quantitatively. As annealing proceeds, the intensity of α-fiber orientation components decreases, but the intensity of γ-fiber components increases slightly and maintains at a higher value. The volume fraction of111 and112<110> decreases as recrystallization proceeds, while the volume fraction of100 and random orientation textures increases. Compared with the cold-rolled state, it is observed that the volume fraction of main textures has greater changes in annealing at low temperature than at high temperature. Finally, variations in the volume fraction of111,112<110>,100 and random orientation textures during recrystallization were described by a JMAK kinetics model.
