Sažetak
The mathematical model and computer simulation for the prediction of mechanical properties of case hardened steel was developed. Because of wide range of applicability and ease of use of finite volume method (FVM), this numerical method was suitable to create integrated computer program for simulation of diffusion of carbon, transient temperature field, microstructure transformation and mechanical properties during case hardening of steel. The computer simulation of mechanical properties of case hardened steel is consisted of numerical calculation of diffusion of carbon, calculation of transient temperature field during the case hardening and hardness after the quenching of steel. The hardness of case hardened steel has been predicted by conversion of calculated time of cooling from 800 °C to 500 °C to the hardness. After that, algorithm for prediction of hardness distribution of case hardened steel was found out. The established procedure was applied in computer simulation of case hardened steel.
