WebSep 30, 2024 · A grain boundary (GB) is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material. A grain boundary is a general planar defect that separates regions of different crystalline orientation ... Webnanometer scale), grain boundary accom-modation remains dominant, but grain boundaries start to also emit partial dislo-cations. As grain sizes increase, several partial or imperfect dislocations nucleate in different regions of the grain boundary, in contrast to the emission of full or per-fect dislocations known from coarse grained metals (15).
