ABSTRACT:
Different metallic materials are joined in such a manner that friction heat generated by friction between a rotating probe made of a hard material and one of the metallic materials having a lower mechanical strength or a lower melting point than the other to effect plastic flow of the one material and the probe is inserted into a pit formed in a joint zone of the other material to fill the pit with the plastic flow material.
