Purpose: The research purpose is to upgrade the mathematical modelling and computer simulation of quenching of steel. Design/methodology/approach: The computer simulation of steel hardening is consisted of numerical calculation of transient temperature field in process of cooling, and of numerical calculation of mechanical properties. The hardness has been predicted by the conversion of calculated...
Purpose: The computer simulation of mechanical properties of quenched and tempered steel was investigated. The established method of computer simulation was applied in prediction of mechanical properties of workpiece with complex form. Design/methodology/approach: The method of computer simulation of mechanical properties of quenched and tempered steel was established by theoretical analysis of relevant...
Purpose: The performance and possibilities of application of modified Jominy-test (JMC®-test) in computer simulation of high-hardenability steel quenching were investigated. JMC®-specimen and cylindrical specimen has similar cooling curves if the cylindrical specimen has been quenched in oil or cooled in air. Design/methodology/approach: The performances of investigated JMC®-test have been estimated...
W niniejszej pracy opisano sposób opracowania zależności umożliwiających wyznaczenie danych (własności termofizycznych i wartości parametrów funkcyjnej zależności twardości od kinetyki stygnięcia) niezbędnych do symulacji pola twardości hartowanych odlewów staliwnych na podstawie składu chemicznego staliwa.
W niniejszej pracy opisano próbę opracowania zależności umożliwiających wyznaczenie danych (własności termofizycznych i wartości parametrów funkcyjnej zależności twardości od kinetyki stygnięcia) na postawie składu chemicznego staliwa. Dane te umożliwiają symulację pola twardości hartowanych odlewów staliwnych.
