Vacuum furnace has been used for brazing repair of aerospace components, but it is a
slow process which typically takes a few hours. The prolonged heating and cooling cycles could
cause some adverse effects on the components such as excessive grain growth. A rapid brazing
technique using induction coil was studied to evaluate its suitability for localized repair. Induction
brazing of Inconel 718 was carried out using AMS 4777 brazing paste at different temperatures
(950 C, 1050 C and 1150 C ) for various durations (2 min, 10 min and 20 min). Microstructure
and microhardness were evaluated. The experimental results show that brazing at 1050 C leads to
desirable microstructures in a short period of merely 2 min. The study demonstrates the potential
application of induction brazing for rapid localized aerospace repair.
