PURPOSE: To provide a method for bonding a plurality of dissimilar metals without producing any brittle intermetallic compound on a bonding interface. CONSTITUTION: In a method for bonding dissimilar materials, energy is given to one material 2 by using a probe 1 rotating at high speed, the material 2 is softened by the friction heat and plastically fluidized, and the material 2 is filled into a recess 4 formed in the other material 3 in advance by pushing or moving the probe, and thus the dissimilar materials are bonded to each other. Since only the material 2 is plastically fluidized, but the material 3 is not plastically fluidized, the materials 2 and 3 are not mixed with each other, and production of any intermetallic compound on the bonded interface can be suppressed. |
