| Abstract Scope |
The role of stacking fault energy on the recrystallization behaviour of the Ni-Co (20, 30, 40, and 60 wt.% Co) alloy system has been explored. In this alloy system, the normalized SFE of the alloy decreases linearly with Co content and varies from high to a medium SFE regime. In recrystallization experiments, it was found that the recrystallization texture of these alloys is dominated by the α-fiber components. Moreover, weak γ-fiber and cube-fiber are also present. The extent of growth selectivity was found to be substantial in Ni-Co alloys at the later stages of recrystallization. Different components of the recrystallization texture in Ni-Co alloys could be related to the extent of heterogeneous deformed microstructural features such as micro/shear-bands, and the phenomena of annealing twinning. These experimental findings were used to develop a model and predict different phenomena during recrystallization process such as evolution of microstructure and texture of recrystallized grains. |
