| Abstract: | The stainless steel/carbon steel chips composite plates were prepared by the method of pressing at room temperature and three passes of vacuum hot rolling with the reduction rate of 40%, 40% and 50%, respectively. The relationship between the pressing forces at room temperature and the relative density of carbon steel chips was studied. The mechanics properties and microstructure of the composite plates with relative density of carbon steel chips 50%, 60%, 70% and 80% were analyzed before rolling. The results show that the brittle inclusions formed at the combined interfaces of the composite plate with 50% relative density of carbon steel chips before rolling hinder the diffusion of Cr, the composite plates do not produce metallurgical bonding, and the bonding strength is lower than the national standard of China. Inclusions at other relative densities are crushing, the composite plate meet the requirements, and the greater the relative density of carbon steel chips, the thicker the decarburization layers of the carbon steel chips layers, the better the metallurgical bonding effectiveness of the composite plates. There are no obvious inclusions at the combined interfaces of composite plates with a relative density of more than 70%. The composite plates with relative density of 70% have the highest tensile strength, reaching 589.97 MPa; the composite plates with relative density of 80% have the best elongation, which is 56.51%. |
