Özet

In this article, oxidation kinetics of carbon steel is investigated with respect to the existence of copper (Cu). It is aimed to figure out the high-temperature oxidation behaviours of Cu bearing steel. Cu induced hot shortness is the main problem of recycling of tramp element containing steels. The experimental temperature range was decided according to the steel deformation process'. Oxidation experiments were conducted between 900 and 1200 degrees C with 100 degrees C intervals in an electrical resistance furnace. High-temperature oxidation kinetics of Cu bearing carbon steel was examined. Topographical surface analysis' of samples were carried out via X-ray diffraction, scanning electron microscopy, optical microscopy. Mass gain rate and kinetical results were algebraically evaluated. Cu segregation on steel surface at elevated temperatures and its behaviour against oxygen were observed.
