An analytical description of overall phase transformation kinetics applied to the recrystallization of pure iron / B.B. Rath in Acta materialia, Vol. 59 N° 20 (Décembre 2011) 

Public ISBD [article]  in Acta materialia > Vol. 59 N° 20 (Décembre 2011) . - pp. 7538–7545 Titre : An analytical description of overall phase transformation kinetics applied to the recrystallization of pure iron Type de document : texte imprimé Auteurs : B.B. Rath, Auteur ; C. S. Pande, Auteur Année de publication : 2012 Article en page(s) : pp. 7538–7545 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Annealing  Nucleation  of  recrystallization  Iron  Kinetics  Deformation  structure Résumé : Experimental studies of recrystallization in deformed single crystals of pure iron are described. The results are used to analyze various parameters associated with the time evolution of the volume fraction of the growing phase during phase transformations in this system associated with the phenomena of nucleation and growth. In addition, using the experimental results, the phenomenon has been modeled by a new approach which may provide a different, and possibly more precise, description of the kinetics of the process. The proposed analytical approach uses easily measured metallographic parameters, obtained from a systematic two-dimensional surface examination, to provide a detailed description on the time dependence of nucleation, nucleation rate, growth rate and interfacial migration and compared with the classical approach based on Kolomogrov formalism.
