Abstract
A method for the manufacture of a brazed body including forming a multi-layer assembly having: a first material capable of forming a first oxide and having a melting temperature higher than 660° C.; a first reducing metal adjacent the first material, the reducing metal capable of reducing at least a portion of the first oxide on the first material a braze adjacent to the reducing metal; and a second material adjacent the braze, the second material being a material having a melting temperature higher than 660° C. The method then includes creating a vacuum around the assembly, and heating the assembly to melt the reducing metal and the braze. The assembly is then subject to cooling to thereby form the brazed body.
