Grain boundary 意味
Web結晶粒界（grain boundary）は，異なる結晶方位を持つ隣接粒間の境界である．通常，ある結晶粒中の すべり面は粒界を挟んで不連続であり，通常転位は粒界を通り越えて移動できず，障害となる（図4.3(a)）． WebAug 14, 2007 · The effects of the lattice misorientations at the grain boundaries (GBs) have been included by accounting for the densities of the misfit dislocations at the GBs that accommodate these misorientations. By directly accounting for the misfit dislocations, the strength of the boundary regions can be more accurately represented to account for ...

WebIn materials science, grain growth is the increase in size of grains (crystallites) in a material at high temperature.This occurs when recovery and recrystallisation are complete and further reduction in the internal energy can only be achieved by reducing the total area of grain boundary. The term is commonly used in metallurgy but is also used in reference …
