| Popis: | Describing microstructure evolution in nanocrystalline tungsten requires a quantitative description of the anisotropic grain boundary energy. We present a grain boundary energy function for tungsten that specifies the energy of an arbitrary boundary given its five macroscopic crystallographic parameters. A comparison of measured grain boundary areas and the grain boundary energies given by the function at the Σ11, Σ17b, and Σ33a mis-orientations, which are problematic to determine by measurement or atomistic calculations, reveals inverse correlations that are similar to what have been observed in microcrystalline metals. |
