Vacuum Brazing

First, we describe vacuum brazing and vacuum soldering. Then, we demonstrate how vacuum assists in reducing specific metal oxides, significantly enhancing the wetting of the braze material. Examples of metal-to-metal brazing and soldering are provided.

Vacuum brazing Mo using Ti–Ni–Nb braze alloys

International Journal of Refractory Metals and Hard Materials, 2011
Abstract A novel approach of brazing Mo using three clad Ti–Ni–Nb foils, 40Ti–35Ni–25Nb, 50Ti–35Ni–15Nb and 60Ti–15Ni–25Nb in wt.%, has been performed in the experiment. Similar microstructural evolution of the joint is observed for three foils. The joint using 60Ti–25Ni–15Nb foil brazed at 1250 °C for 600 s demonstrates the highest bending strength ...
