Simulation of microstructure and properties evolution of micro alloyed steel during hot deformation by cellular automaton

Journal Article


Abstract


  • A model for prediction of the dynamic recrystallization microstructure and properties evolution of hot

    deformed austenite for micro alloyed steel by cellular automaton (CA) was developed. The theoretical

    modeling of dynamic recrystallization was on the basis of dislocation density, and the nucleation and grain

    growth of dynamic recrystallization were considered. The microstructure evolution of austenite dynamic

    recrystallization, such as the grain shape, grain size and volume fraction, was predicted quantitatively and

    visually described. Moreover the distribution and variation of the dislocation density and flow tress were

    obtained. Meanwhile, the microstructure and variation of the flow tress of micro alloyed< steel during hot

    deformation were measured by experiments. The measured results were in good agreement with the CA

    calculation results.
