Abstract
Plastic flow behavior of the SNCM8 steel was investigated by performing hot compression tests within the temperature range of 850 ˚ C to 1200 ˚ C and strain rates of 0.01 s − 1 to 10 s − 1 . Constitutive modeling based on dynamic recrystallization was established, in which Cingara equation was applied to represent work hardening up to peak stress and Avrami equation to describe dynamic softening beyond peak stress up to steady state. It was found that stress-strain responses predicted by the combined model fairly agreed with experimentally resulted curves for the particular conditions. The correlation coefficient ( R ) of 0.9485 and average absolute relative error ( AARE ) of 2.3614% was calculated for the modeled flow curves.
