Grain-boundary topological phase transitions
WebNov 3, 2024 · Grain-Boundary Topological Phase Transitions. The formation and migration of disconnections (line defects constrained to the grain boundary (GB) plane with both … WebGrain boundary motion can be driven by a chemical potential that jumps across a GB or by shear applied parallel to the GB plane; the driving force has three components. Hence, the GB mobility must be a tensor (the off-diagonal components indicate shear coupling).
