WebWhat is grain boundary? Most inorganic materials in nature (e.g. common metals, many ceramic, rocks) are polycrystalline structures, which are made of a large number of single crystalites (or grains). Also, the interface of two grains is called the grain boundary. The grain boundaries in a material's microstructure have significant effects on ... WebThe grain size of a UNCD film determines the sp 2 and hydrogen content. It follows that smaller grains result in higher grain-boundary (GB) areas, which in turn leads to higher …
