WebJan 29, 2024 · Materials scientists have long recognized that grain boundaries (GBs) can be treated as interfacial phases that are thermodynamically two-dimensional (2-D). [ 12, 13] In 1968, Hart first proposed to treat GBs as 2-D interfacial phases. [ 14, 15] Subsequent models developed by Hondros and Seah, [ 16, 17] Cahn and Kikuchi, [ 18 - 21] Clarke et … Grain boundary sliding (GBS) is a material deformation mechanism where grains slide against each other. This occurs in polycrystalline material under external stress at high homologous temperature (above ~0.4 ) and low strain rate and is intertwined with creep. Homologous temperature describes the operating temperature relative to the melting temperature of the material. There are mai… WebPopular answers (1) Interesting question.
