  • Measurement and evaluation of the quenching intensity of quenching agent for hardening
    Grum, Janez, 1946- ; Božič, Slavko, 1971- ; Lavrič, Roman
    Mechanical properties of a machine part depend on the kind of steel used and heat treatment applied. To this end various methods of determination of through-hardenability of steels, such as Jominy ... and Grossmann methods, have been developed. The Jominy hardenability curves have made it possible to set up appropriate criteria of evaluation of through-hardenability and mutual comparison of steels. The paper presents results regarding cooling intensities of some oils of domestic production and of polymeric water solutions. Numerous temperature measurements on heat-treatment steel specimens with different masses were made. They provided very important information on cooling rates for a material when using different quenching agents. The cooling rates attained for a steel permit, for a given steel with a known continuous cooling diagram, determination of microstructural changes, and consequently prediction of mechanical properties of the steel.
