Introduction With the development of modern industry, compound materials are widely used in various industrial fields.
Because of the different physics properties of the two materials, it is difficult to produce no heat crack and porosity joints with sufficient strength by fusion welding methods.
Therefore much interest exists in the use of solid state welding in which the development of intermetallic compounds at the joint interface is avoided and nice welding performance of dissimilar materials can be obtained.
