Computer simulation of mechanical properties of steel dies

The algorithm of estimation of yield strength and fracture toughness on the base of steel hardness HV has been made. The hardness distribution in quenched die was estimated based on relevant time of cooling 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 computer simulation of mechanical properties was made for steel 60WCrV7 (DIN). It can be concluded that by proposed method mechanical properties of quenched and tempered steel dies can be successfully calculated.
