Computer simulation of microstructure and mechanical properties of cast steel
The research purpose is to upgrade the mathematical modelling and computer simulation of casting of steel. Based on theoretical analyses of physical processes which exist in casting systems the proper mathematical model is established and computer software is developed. On the basis of control volume method, the algorithm for prediction of mechanical properties and microstructure distribution in steel casting has been developed. The computer simulation of casting of steel is consisted of two parts: numerical calculation of transient temperature field in process of solidification and cooling of casting to the final temperature, and of numerical calculation of mechanical properties. The hardness and microstructures of casting has been predicted based on CCT diagrams. Physical properties that were included in the model, such as heat conductivity coefficient, heat capacity and surface heat transfer coefficient were obtained by the inversion method. The algorithm is completed to solve 3-D situation problems such as the casting of complex cylinders, cones, spheres, etc. The established model of steel casting can be successfully applied in the practice of casting.
