Sažetak
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 by comparison of cooling curves of JMC®-specimen and cylindrical one cooled in different quenchants. Findings: Based on the sufficiency of both, time of cooling and similarity of cooling curves of investigated workpieces and JMC®-specimen it can be concluded that JMC®-test can be accepted as very useful test for estimation of the hardness of quenched workpieces made of high-hardenability steels. Research limitations/implications: The cooling curves of JMC®-specimen and the cooling curves of cylindrical specimens have been given by computer simulation and more experimental researches are advisable. Practical implications: The simulation of quenching based on modified Jominy-test can be applied for steels with high hardenability. This method of simulation is especially suitable for tools and dies steels. Originality/value: Using the results of simple modified Jominy-test (JMC®-test) in numerical modeling of steel quenching it is possible to simulate hardness in quenched specimen of high-hardenability steel.
