    Abstract

    The possibility of the application of a modified Jominy-test in the computer simulation of quenching of steels for tools and dies has been investigated. The performance of an investigated modified Jominy-test in the simulation of quenching of tools and dies was estimated by a comparison of the cooling curves of a modified Jominy-specimen (JM®-specimen) and a cylindrical specimen. The hardness distribution in a quenched specimen was estimated based on a relevant cooling time from 800 to 500°C, as well as on the results of a modified Jominy-test. The characteristic cooling time, relevant for the results of quenching, was predicted by the computer simulation of quenching of both the JM®-specimen and cylindrical specimen. Mechanical properties of quenched steel directly depend on the degree of quenched steel hardening. The algorithm of the estimation of yield strength and fracture toughness on the base of steel hardness is established in this paper. Using the established algorithm, the mechanical properties of quenched and tempered die steel were estimated by computer simulation. It was found that the modified Jominy-test can be applied in the simulation of quenching of high hardenability steel more successfully than by the original Jominy-test.
