Résumé

This paper studied the influence of quenching and tempering steel structures on the thermal conductivity for OSC 11 steel. For the experiment we used samples that were subjected to heat treatment quenching and tempering at 200˚C and at 500˚C. To emphasize the structure and structural changes in both the sample and the untreated samples, micrographs and photos were made by scanning electron microscopy. Measured conductivity results were presented graphically and studied to highlight their influence on the hardening structure.
