The effects of temperature on the microstructure and composition of surface oxidation layer of copper age-hardening steel were investigated by SEM-BSE. The results show that the thickness of oxidation layer increases and the structure changes as temperature rising. The whole oxidation layer can be divided into three parts: iron oxides layer, Cu-rich phase layer and transition layer. The Cu in the oxidation layer is in the form ofCu Ni-rich phase. As the temperature rising, the microstructure and composition of the transition layer change.
