摘要：

Titanium (Ti)/steel clad plates with interlayer material of interstitial free (IF) steel, vanadium (V) and IF steel + V were successfully fabricated by hot roll bonding method at temperature of 850, 900 and 950 degrees C. Tensile shear test and tensile test were performed to evaluate the mechanical properties of the Ti/steel clad plates. The interfaces and the fracture surfaces of Ti/steel clad plates were carefully characterized by scanning electron microscopy, energy-dispersive spectroscopy and X-ray diffraction. The results reveal that the interlayer materials have influence on the compounds at the Ti/steel interfaces. Carbides are detected at the interfaces of Ti/steel with single IF steel or V interlayer. The formation of carbides impairs the shear strength of clad plates. a phases instead of carbides are observed at the interface of Ti/steel clad plate with IF steel + V interlayer, which is beneficial for the tensile shear strength. Rolling temperature also has significant influence on mechanical properties of Ti/steel clad plates. The thickness of a phase increases with the increase of rolling temperature. Thick a phases impair the mechanical properties of the Ti/steel clad plate.
