Abstract:Heat transfer theory, the initial conditions and boundary conditions were pointed out briefly. A quantitative modeling of latent heat converting to equivalent heat capacity was established on stereology, and three-dimensional cooling temperature field was simulated by the dynamic heat transfer coefficient. The results show that the simulation temperature fits the actual temperature. The model provides a theoretical basis of heat treatment for other types of alloys.
Key words: temperature field; simulation; phase transition
