    • 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.
    • 本发明提供一种将两个金属构件接合到接合的金属构件中的方法。 该方法包括以下步骤: 施加具有比第一金属构件表面上的两个构件更高的熔点的钎焊材料,并加热它们以在所述表面上形成钎焊材料,并且在第一构件的表面区域内的钎焊材料下面的钎焊扩散层 ; 然后在比钎焊材料的熔点高的加热温度下挤压钎焊材料插入其中的第一和第二金属构件,以将两个金属构件的两个接触表面之间挤出熔融钎料 因此,两个金属构件通过形成在两个表面中的钎焊扩散层连接到接合的金属构件中。 特别地,第一金属构件可以包括铁基合金,并且第二金属构件可以包括铝基合金,并且钎焊材料可以是诸如Zn-Al共晶合金的含锌材料。
