Prediction of Tempered Martensite Hardness Incorporating the Composition-Dependent Tempering Parameter in Low Alloy Steels

抄録

We investigated a composition-dependent tempering parameter for more accurate prediction of tempered martensite hardness in low alloy steels. The proposed composition-dependent tempering parameter decreased with the addition of alloying elements related to the activation energy for tempering. The tempered martensite hardness calculated using the composition-dependent tempering parameter showed a reliable accuracy compared with experimental data.
