In the present work, modeling of hot deformation behavior was carried out in medium carbon low alloy steels having dendritic microstructure as starting material. Uniaxial hot compression tests were performed on Gleeble-3800 thermomechanical simulator over a wide range of temperatures (1200C to 1050C) and strain rates of (0.2s-1 to 2s-1). The deformation behavior and strain rates were selected on the basis of actual ingot break down process during forging. The results from compression tests were taken as the basis for determination of the analytic function of flow stress for deriving Hensel-Spittel equations. Analysis of the effect of strain rate and temperature on material flow behavior compared Hansel- Spittel and experimental data. The modeling equations were developed in order to find the dynamic recrystallization volume fraction. The comparative study of both these models is presently been analyzed in the framework of classical nucleation theory.
