WebThe grain-boundary energies of individual boundaries have been determined by the analysis of the shapes of grain-boundary grooves. The effects of surface-energy anisotropy are fully taken into account. The results indicate that only boundaries associated with high-coincidence orientations (∑3 and ∑11) have significantly lower … WebGrain boundary complexion transitions can lead to rapid changes in the macroscopic properties of polycrystalline metals and ceramics and are responsible for a variety of …
