ABSTRACT:
Substrates made of a metal or an alloy are bonded by coating a brazing flux incorporating a metallic powder or a metal compound powder on the surface of the substrate having a melting point of higher than 700.degree. C.; and heating them at a temperature higher than a melting point of the flux but lower than a melting point of the metal of the metallic powder or the metal compound powder whereby a molten crystallization and a mutual diffusion are caused between the substrates and the metal activated by the molten flux.
