Grain boundary complexion transitions

WebThe Maryland Court of Special Appeals agreed, and held that the language of the senior deed, which described the course of a boundary line as "continuing in a straight line," … 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.
