Computer simulation of mechanical properties of steel for tools and dies

Each type of engineering component failures is related with characteristic mechanical property, and in designing of engineering components it is necessary to understand types of failure. Generally, engineering components can fail due to fracture, or due to excessive deformation. Yield resistance and crack resistance are fundamental properties, which are used in design of safety engineering components applications. The algorithm of estimation of yield strength and fracture toughness on the base of steel hardness will be presented in this paper. The hardness distribution in quenched specimen was estimated based on relevant cooling time from 800 °C to 500 °C, as well as on results of modified Jominy-test, which is designed for hardenability prediction of high-hardenability steels. The mechanical properties was estimated after steel quenching and tempering. The computer simulation of mechanical properties was made for steel 60WCrV7 (DIN).
