EVALUATION OF BRAZING ALLOYS FOR THE FABRICATION OF INCONEL 718 HONEYCOMS SANDWICH PANELS

摘要

A nickel base structural alloy, Inconel 718, has been considered for use in the fabrication of honeycomb structures capable of sustained operation at elevated temperatures. Four gold-containing brose alloys ware selected for compatibility tooting with Inconel 7l8 base natal.nFrom the results of these tests premabyase brace alloys appeared to be suitable for honeycomb structure brawling with Inconel 718 as base rental Ho evidence was found to indicate that either. of these braze alloys are susceptible to crevice corrosion. braes alloys were eliminated from testing because of inferior wet ability and flow characteristics.
