Abstract:

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 braze alloys were selected for compatibility testing with Inconel 718 base metal. From the results of these tests braze alloys appeared to be suitable for honeycomb structure brazing with Inconel 718 as base metal. No evidence was found to indicate that either of these braze alloys are susceptible to crevice corrosion. Two other braze alloys were eliminated from testing because of inferior wettability and flow characteristics.
