ABSTRACT:
The present invention comprises a method of manufacturing a brazed body. The method comprises forming a multi-layer assembly comprising: 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 comprising a material having a melting temperature higher than 660° C. The method then comprises 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.
