Abstract

In this work we have studied the effect of the carburizing duration on the evolution of the thermal and mechanical properties of the 10NiCr11 steel. The thermal properties are determined by the photothermal deflection technique and it was shown that the thermal conductivity as well as the thermal diffusivity decrease with the carbon fraction in the steel unlike the Vickers hardness which increases. From this study we have established an empiric mathematical formula between Vickers hardness, the thermal properties, and the carburizing duration which permit to deduce the Vickers hardness value without needing to measure it.
