Abstract: As a non-carbide forming element,copper is widely used in iron and steel materials. On the one hand,the addition of copper and subsequent heat treatment lead to hot embrittlement,which will deteriorate the hot working performance of steel;on the other hand,copper is segregated in steel to improve the corrosion resistance of steel. The phenomenon of copper segregation in copper-containing steel was summarized,the effects of heating temperature,deformation and alloying elements on copper segregation were reviewed on the basis of briefly introducing the reasons of copper segregation in steel.Adding appropriate alloying elements to steel and optimizing the heating system and deformation process can control the local segregation behavior of copper in steel,optimize the performance of materials,which can provide references for practical applications.
