Jominy hardness conversion table
http://www.carbidedepot.com/formulas-hardness.htm Nettet15. apr. 2024 · Abstract. An improved Jominy curve hardness model was built for carburizing-quenching process. In contrast to the other hardness model, it avoids the computational heterogeneity of phase transformation and has strong operability. Finally the model was applied to the carburized Jominy and gear specimens of 17CrNiMo6 steel.
