In this paper, we examine the nucleation and growth behavior of a highly deformed Incoloy 800H/HT. We also investigate the effect of rolling path (i.e. unidirectional and cross rolling) on the recrystallization mechanism and subsequent annealing texture of Incoloy 800H/HT. We used micro- and macro-texture measurements to investigate the evolution of texture components in various nucleation and growth stages. We studied the recrystallization kinetics by means of isothermal transformation plots based on recrystallized and softened fractions drawn from orientation imaging microscopy and microhardness measurements. Results show that the recrystallization kinetic after cross rolling (CR) is slower than after the uni-directional rolling (UDR) deformation. Due to different nucleation and growth mechanisms, these samples showed different recrystallization textures. CR samples exhibited a strong brass recrystallization texture while UDR samples showed a combination of Goss, copper and recrystallized brass View the MathML source components.
