Misorientation texture development during grain growth / J. Gruber in Acta materialia, Vol. 58 N° 1 (Janvier 2010) 

Public ISBD [article]  in Acta materialia > Vol. 58 N° 1 (Janvier 2010) . - pp. 14–19 Titre : Misorientation texture development during grain growth : Part II: Theory Type de document : texte imprimé Auteurs : J. Gruber, Auteur ; A.D. Rollett, Auteur ; G.S. Rohrer, Auteur Année de publication : 2010 Article en page(s) : pp. 14–19 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Texture  Grain  growth  Anisotropy  Grain  boundaries  Simulation Résumé : A critical event model for the evolution of number- and area-weighted misorientation distribution functions (MDFs) during grain growth is proposed. Predictions from the model are compared to number- and area-weighted MDFs measured in Monte Carlo simulations with anisotropic interfacial properties and several initial orientation distributions, as well as a dense polycrystalline magnesia sample. The steady-state equation of our model appears to be a good fit to all data. The relation between the grain boundary energy and the normalized average boundary area is discussed in the context of triple junction dynamics.
