WebJan 29, 2024 · Grain boundaries (GBs) can be treated as two-dimensional (2-D) interfacial phases (also called “complexions”) that can undergo interfacial phase-like transitions. As bulk phase diagrams and calculation of phase diagram (CALPHAD) methods serve as a foundation for modern materials science, we propose to extend them to GBs to have … 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 …
