Abstract
Titanium/steel clad plates were produced through vacuum hot rolling, employing varied surface treatments, assembly techniques, and heating temperatures. The study investigated the interfacial microstructure of different preparation methods, and six specimens were extracted from both the edge and central regions of each plate for shear testing to evaluate the interfacial bonding strength. Water belt machine-processed surfaces demonstrated excellent flatness without noticeable concavity or convexity, exhibited no obvious oxides, and achieved the highest interface bonding strength (239 MPa). The titanium/steel/titanium clad plates showed lower strength compared to those produced by the steel-titanium-titanium-steel method, interfacial oxides increased with temperature, reducing the bonding strength to 136 MPa at 950°C. In contrast, the steel-titanium-titanium-steel plates exhibited peak bonding strength of 266 MPa at 900°C.
