WebThe grain boundary refers to the outside area of a grain that separates it from the other grains. The grain boundaries separate variously-oriented crystal regions (polycrystalline) in which the crystal structures are identical. Grains and Boundaries Source: U.S. Department of Energy, Material Science. DOE Fundamentals Handbook, Volume 1 and 2. WebGrain boundary character distribution (GBCD) and grain boundary (GB) connectivity have shown a close relationship with these material properties. The coincidence site lattice (CSL) model is employed to describe GBCD by classifying grain boundaries (GBs) as low-Σ CSL boundaries (CSLBs, Σ = 1-29) and general boundaries including high-Σ CSLBs ...
