Abstract:
The receipt of honeycomb core material of A-286 and Rene 41 occasioned checking of previously obtained brazing results, using the foil gage materials. This work revealed that all the high temperature brazing alloys previously studied eroded and embrittled the honeycomb core during the brazing operation. Experiments to overcome these difficulties resulted in the successful brazing of 6 in. by 6 in. panels in A-286. No brazing alloy was found that is fully satisfactory for brazing honeycomb sandwich panels of Rene 41. The results of high temperature oxidation and creep tests indicate that Rene 41 will require some form of surface protection when used in thin sheet form at 1600 deg F. The results of the tests conducted on honeycomb sandwich panels of A-286 brazed with an alloy of 65.2 Cu, 21.7 Mn, 8.7 Co, and 4.35 Ni indicate that this combination merits further investigation.
