An application of modified Jominy-test in computer simulation of quenching of cold work tool steels

The possibility of application of modified Jominy-test in computer simulation of quenching of cold work tool steels has been investigated. Because of high hardenability of cold work tool steels thre are limits in application of original Jominy-specimen in simulation of quenching of steels. The modified Jominy-test was designed for prediction of hardenability of cold work tool steels. The performance of investigated modified Jominy-test in simulation of quenching of dies was estimated by comparison of cooling curves of modified Jominy-specimen (JM&reg ; -specimen) any cylindrical specimen. The characteristic time, relevant for results of quenching was predicted. Modified Jominy-test can be applied in simulation of quenching of steel with higher hardenability rather than original Jominy-test.
