摘要：

The impacts of the vacuum brazing conditions, including the flux type, filler metal, base pressure, thermal properties of jig and set, and brazing technologies available, on the microstructures, chemical contents and mechanical properties of the aluminum alloy parts to be brazed were experimentally studied. The results show that among other things, the working pressure and thermal capacity of the jig-set strongly affect the vacuum brazing of aluminum alloy. We suggest that the working pressure lower than 1×10-3Pa and a jig-set made of material with low heat capacity be the fundamental requirements for the vacuum brazing.
