Texture evolution of annealed Fe-19Cr-2Mo-Nb-Ti ferritic stainless steel

Texture evolution of Fe-19Cr-2Mo-Nb-Ti ferritic stainless steel was investigated under different annealing temperatures. After cold rolling, the in-grain shear bands provide more recrystallization nucleation sites to {111} recrystallization grains with high Taylor factor during recrystallization. As the annealing temperatures increase, the average size of annealed grains and precipitates gradually increase, and 1050 degrees C annealed grains are dominated by the uniform and equiaxial {111} recrystallization grains favourable for the formability. Accordingly, as the annealing temperatures increase, the average plastic strain ratio of annealed sheets rises to 1.71 monotonically. (C) 2018 The Authors. Published by Elsevier B.V.
