Mathematical Modelling and Computer Simulation of Quenched and Tempered Steel Properties
The algorithm of estimation of mechanical properties based on steel hardness has been established. The established procedure for estimation of quenched and tempered properties of steel has been applied in computer simulation of mechanical properties of quenched and tempered steel workpiece of complex form. Numerical modelling of hardness distribution in as-quenched steel specimen was performed by involving the results of simple experimental test, i.e., Jominy-test. Hardness of quenched and tempered steel has been expressed as function of maximal hardness of actual steel, hardness of steel with 50 % of martensite in microstructure, according to the time and temperature of tempering. Experimental investigation has been performed on low alloy steel. After that distribution of other relevant mechanical properties was predicted based on predicted as-quenched hardness of steel. By experimental work was found out that yield strength and fracture toughness of quenched and tempered steel workpieces can be successfully predicted by proposed method. The proposed computer simulation method could be applied in failure prevention.
