Abstract:The evolution of microstructure seriously influences the forming processes and the quality of forgings in metal hot forming processes, it is therefore desirable to gain information on the microstructure evolution of a process by means of computer simulation, not by conventional trial and error method that is time consuming, expensive and does not always lead to optimum results. Models for microstructural simulation and prediction were set up according to the evolution of microstructure during hot forming and cooling processes. The expanding-extrusion complex hot forming and cooling processes, as an example, were simulated.


Key words: metal hot forming; microstructural simulation; quality prediction
