Abstract: Based on the principle of heat transfer and phase transformation, a computer program has been written in prodigal the heating and cooling temperature fields, microstructure and mechanical properties of large rotor and shell ring. The feature of this paper is to take into account the effect of the enthalpy of transformation on the temperature fields and to predict the mutual influenced process of both temperature change and phase transformation at the same time. The temperature dependents of thermo physical properties and the effect of grain size on phase transformation are considered in this program as well.
