Sažetak
The mathematical model for prediction of microstructure composition of heat treated steel welded joint was developed. Also, influence of tempering on welding joints properties was studied. The finite volume method (FVM) was applied to create integrated computer program for simulation of transient temperature field, microstructure transformation and mechanical properties during heat treatment and welding of steel. The computer modelling of mechanical properties and microstructure of welded joint is consisted of numerical calculation of transient temperature field in process of cooling, and of numerical calculation of hardness. The computer simulation of hardness of welded joint is based on both, CCT diagrams and the thermo-kinetic expressions using linear alignment with the actual chemical composition. Microstructure and hardness of welded joint has been predicted based on calculated characteristic time of cooling from 800 °C to 500 °C, (t8/5). Results of steel welding were estimated by taking into account the process of reheating of workpiece during the welding. The established procedure was applied in computer simulation of heat treatable steel welded joint.
