Abstract—Cladding of steel with titanium alloys is used widely in aerospace, chemical and nuclear industries, to improve corrosion behavior and reduce production costs. Roll bonding is one of the solid state processes to produce this combination. In this research the high quality bonding of hot roll bonding of titanium on steel substrate was investigated in terms of metallurgical and mechanical properties. The effect of copper interlayer on preventing inter-diffusion was also evaluated. The microstructure at interface was observed by an optical and scanning electron microscope and the presence of intermetallic phases in the reaction zone was examined by X-ray diffraction on the fracture surfaces of the joints. The experimental results showed that the volume fraction of intermetallics may be controlled effectively using cupper interlayer, because there is not enough time for interdiffusion of the elements. Total thickness of intermetallic layers and microhardness at the interface increased with increasing bonding temperature.
