Abstract
Abstract
The increasing demands on heavy plates made of high-strength structural steels for heavy machine construction require increasingly extensive and faster systems for a reliable prediction of the mechanical-technological properties of the plates after hardening and tempering. Based on the results of Jominy end quench tests on about 100 steels, the computer program jominy was developed for high-strength steels to calculate the hardness acceptance and hardenability as well as the tempering behavior after accelerated cooling. Based on a known chemical analysis, the expected hardness can be calculated for any sheet thickness and position over the sheet cross section. jominy is intensively used for the optimization and development of materials and heat treatment processes to provide tailor-made products.
