Sažetak
Prediction of working stress of quenched and tempered steel workpiece has been investigated. The working stress was characterized by yield strength, fracture toughness and fatigue resistance. The method of computer simulation of working stress was applied in workpiece of complex form. Fracture toughness and fatigue limit are depended on microstructural constituents, and distribution of the usual intermetallic particles and non-metallic inclusions. Fatigue resistance of quenched and tempered steel is achieved by eliminating coarse alloy carbides present in steel. Properties of matrix may also have an important influence on fracture and fatigue proper behaviour. Most high-strength materials are fracture and fatigue limited. Fatigue strength is directly proportional to the difficulty of dislocation cross slip. Grain size has its greatest effect on fatigue life. The algorithm of estimation of yield strength and fracture toughness was based on steel hardness, HV. Numerical modelling of hardness distribution in quenched and tempered steel has been performed by involving the results of simple experimental test, i.e., Jominy-test. Yield strength and fracture toughness distributions have been predicted using the Hahn-Rosenfield approach. Fatigue threshold was estimated based on predicted microstructure and hardness. It can be concluded that working stress of quenched and tempered steel workpiece can be successfully predicted by proposed method. The further experimental investigations are needed for final verification of established model. The mathematical model has been applied in failure analysis of a quenched and tempered steel shaft. For efficient estimation of fatigue resistance, additional data about microstructure are needed.
