Titanium cladding on steel leads to the creation of properties such as resistance to corrosion that contribute to a widespread application of this metal composite in industries such as nuclear, chemical, aerospace, and biomaterial. One of the solid-state bonding methods to apply such a clad is to use the roll bonding method. In this paper, quality of the titanium cladded on carbon steel was studied in terms of metallurgical, mechanical properties and the effect of the copper interlayer on the metallurgical properties of bonding. The interface between the clad and the base metal was studied using a scanning electron microscope and light microscope and the phases formed were identified by X-ray diffraction analysis. The results showed that an increase in the bonding temperature increased the thickness of the intermetallic compounds, increased the hardness at close distances to the interface, and reduced the adhesion of the titanium cladded to the base metal.
