Investigation of microstructure prediction during experimental thermo-mechanical plate rolling

In this study results of experimental and theoretical research of modeling of microstructure in hot rolling process of steel carbon plates with niobium are presented. Models describing kinetics of recrystallization of a deformed austenite and precipitation of niobium carbon-nitrides were verified in semi-industrial conditions. The main aim of the experimental study made in present paper were determination of distributions of microstructure parameters after partly steps of thermo-mechanical steel rolling.
