Role of lattice strain on thermal stability of a nanocrystalline FeMo alloy / A. Molinari in Acta materialia, Vol. 58 N° 3 (Fevrier 2010) 

Public ISBD [article]  in Acta materialia > Vol. 58 N° 3 (Fevrier 2010) . - pp. 963-966 Titre : Role of lattice strain on thermal stability of a nanocrystalline FeMo alloy Type de document : texte imprimé Auteurs : A. Molinari, Auteur ; S. Libardi, Auteur ; M. Leoni, Auteur Article en page(s) : pp. 963-966 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Mechanical  milling  X-ray  diffraction  Nanocrystalline  materials  Iron  alloy  Grain  growth Index. décimale : 669 Métallurgie Résumé : The thermal stability of a nanocrystalline Fe–1.5 wt.% Mo powder milled with nano-SiO2 was investigated in situ by synchrotron radiation X-ray diffraction. Crystallite size is stabilized by the grain-boundary strain, therefore grain growth starts only after a certain amount of this strain has been released. The phenomenon was rationalized by a micromechanics approach, which considers the equilibrium between forces acting on the grain boundary surface.
