    Abstract

    We have developed a theoretical and experimental model for imaging heat-treated steel hardness profiles. An analytical solution to the heat equation is presented as a guide to measurements, which are focused on prospecting both mechanical parameters and thermal local properties, indexed on the carbon-iron ratio along treatment depth. We tried to prove that the existence of a simple correlation between treated steel mechanical and thermal characteristics rises only beyond a critical carburizing depth. Comparison between several results allowed us to evaluate this critical depth and establish a simple correlation between treated steel HV microhardness and thermal diffusivity, in a particular case of surface hardening treatment.
