WebMay 22, 2016 · We investigate the mechanisms of incipient plasticity at low angle twist and asymmetric tilt boundaries in fcc metals. To observe plasticity of grain boundaries independently of the bulk plasticity, we simulate nanoindentation of bicrystals. On the low angle twist boundaries, the intrinsic grain boundary (GB) dislocation network deforms … WebGrain boundary complexion transitions are difficult to predict a priori and typically occur independently of bulk phase transformations, i.e. at different values of tempera- ture, pressure or composition. Therefore, they often result in unexpected and seemingly inexplicable phenomena.
