Abstract Scope |
The serrated morphology of moving recrystallization fronts is usually to inhomogeneous distribution of stored energy of deformation that manifests as an organized dislocation substructure. Current understanding is based on continuum description of the motion of the high angle grain boundaries that form the moving font. Here, we use a combination of stability theory and computations to show that the effect of impurities is amplified by deformation energy that is also a source of impurities, resulting gradients in impurity segregation along the front. We present results on the combination of impurity concentration and variations in stored energy of deformation that offer control over the morphology of the recrystallization fronts, and in turn the recrystallization kinetics. |
