Abstract
The present invention provides a method for joining two metal members into a joined metal member. The method comprise steps of; applying a brazing material having a higher melting point than both the members on the surface of a first metal member and heating them to form a brazing material on said surface and a braze-diffusion layer under the brazing material in the surface area of the first member; and, then, pressing the first and another second metal members between which the brazing material is interposed during heating at a higher temperature than said melting point of the brazing material to squeeze the molten brazing material out between both the contact surfaces of both the metal members, therefor the two metal members being joined by the braze diffusion layers formed in both the surfaces into the joined metal member. Particularly, the first metal member may comprise an iron-based alloy and the second metal members may comprise an aluminum-based alloy, and the brazing material may be zinc-containing material such as Zn—Al eutectic alloy.
