Abstract

A model is developed for austenite flow stress dynamics during hot deformation that makes it possible to construct stress-strain curves at different temperatures, and strain rate in relation to steel chemical composition. The model is verified on the basis of independent published data and good convergence of the results obtained is demonstrated. Stress calculations are performed using the model during hot rolling for steel strengthened due to a system of titanium carbide interphase precipitates. The effect of adding titanium and molybdenum on temperature for the end of recrystallization is established.
