Although the two methods have simple processes, the preparation work is complicated, the cleanness of a bonding interface, no oxidation and proper roughness are required to be ensured, the requirements on the relevant properties of the rolled materials are high, the plasticity of the materials cannot be greatly different, otherwise, the materials are easy to be welded or cracked to cause poor properties, and the cost of vacuum diffusion welding is high.
