Predicting steel response to quenching followed by tempering
Heat treatments in the mass of steels. Part 1

To predict a steel's overall response to a hardening and tempering heat treatment, we have an extremely valuable piece of data at our disposal: all the Jominy curves plotted in the tempered state (generally for different tempering temperatures between 500 and 700 C . Such curves have been proposed by Rose and his collaborators [36] and are currently published, for the steel grades standardized in France, in the technical files edited by OTUA [37] .

Such a set of curves for a given steel, based on the "equivalent Jominy distance = f (D, H, r/R)" abacus already described
