Prediction of grain size evolution for low alloyed steels

Abstract

The microstructure of the low alloyed steels after hot plastic deformation and high temperature annealing was described for different regimes of treatment. It was shown, that using of the Avrami- Kolmogorov type equation allows to predict the grain size with accuracy about 7%.
