摘要: Abstract The primary recrystallization of pure metals is mostly characterized by the standard Johnson-Mehl-Avrami-Kolmogorov (JMAK) kinetics. Data stored energy release during deformed copper are presented in this paper. In accordance with discussion literature they demonstrate however that description transformation process rather unsatisfactory. particular, real materials often seem to lack homogeneity state as required JMAK-theory. Hence a model introduced based not on single but distribution activation energies for where each individual follows ideal JMAK-kinetics. shown work very well data and allows satisfactory prediction either isothermal or non-isothermal curves.
