Abstract: Based on the flow deformation rule of titanium/steel clad plate obtained by uniaxial compression tests, hot rolling and heat treatment were conducted on the titanium/steel clad plates under diverse process conditions. Further, the microstructure, interface features and mechanical properties of titanium/steel clad plate treated by different processes were studied systematically. As could be seen from the results, the increase of the thickness ratio and deformation temperature enlarged the difference of the two metal in flowability during the deformation process. According to the stress-strain curve, the prediction model of deformation resistance was established by adopting Levenberg-Marquardt method, and its goodness-of-fit with the measured stress value was 0.961. The titanium/steel clad plate achieved optimal mechanical property under the condition of large reduction within 800 ℃ to 900 ℃. When the heat treatment was carried out at 750 ℃, there existed thick and nonuniform TiC layer at the interface of titanium/steel clad plate. While the TiC layer at interface turned straight and uniform after heat treatment under 850 ℃. The interface layer was further dominated by TiFe, and TiC was distributed on both sides of TiFe, showing a stratified distribution after heat treatment under 950 ℃. Meanwhile, the precipitate of TiC appears along the grain boundary or within the ferrite matrix, and the size of precipitations which could be controlled by raising the cooling rate.
