The microstructure evolution during the cogging, upsetting and hot die forging in the manufacture of IN718 turbine disc has been predicted through coupling the microstructure evolution prediction system developed with a commercial finite element software. The prediction results were in good agreement with the actual ones. Furthermore, the effects of process parameters on the microstructure development during the hot die forging of IN718 turbine disc have been investigated. To design the hot die forging, a uniform function of microstructure has been proposed as the goal function.
