Sažetak
The mathematical model and computer simulation for the prediction of mechanical properties in quenched and tempered steel specimen was developed. In addition, mathematical model for prediction of microstructure composition of quenched and tempered steel was developed. In calculation of both, mechanical properties and microstructure composition the history of cooling was taken in account. Hardness of quenched and tempered steel was expressed as function of maximal hardness of actual steel and representatives of chemical diffusivity. After that, distribution of other relevant mechanical properties can be obtained. The mathematical model is developed for carbon and low alloyed steel. The studied model is based on Jominy test results. The established procedure was applied in computer simulation of quenched and tempered steel workpiece.
