Webgrain-boundary complexion types). The detailed understanding of complexions gained in early work has allowed for new experimental investigations into the thermodynamics of the complexion transitions. Recent results for alumina show that the number of complexion transitions that occur within a fixed volume increases exponentially with WebThis grain boundary complexion transition could explain the grain growth induced by Pd and irradiation previously reported by O'Connell et al. 7, 16 . Therefore, our results suggest that as Pd diffuses through the grain boundary, it can interact with SiC leading to a higher degree of disorder at the grain boundary.
