Mesoscopic simulations of recrystallization

摘要: The application of computer simulation to grain growth and recrystallization was strongly stimulated in the early 80s by realization that Monte Carlo models could be applied problems structure evolution. By extension Ising model for domain modeling magnetic domains Potts (with generalized spin numbers) it then possible represent discretely grains (domains) regions similarly oriented sets material (lattice) points. In parallel with this fascinating development, there also occured notable work on analytical models, especially Abbruzzese Bunge, which has been particularly useful understanding variation texture (crystallographic preferred orientation) during processes. Geometric recrystallization, worked most recently productively Nes et al., have connection size prediction as a result recrystallization. Also, mesh-based developed high degree Kawasaki, Fradkov others, and, rather recently, Humphreys not just but nucleation process These strength they deal essential features grains, i.e. nodes, some limitations when second phases must considered. various approachesmore » processes will reviewed, special emphasis practical approaches implementing model.
