DEVELOPMENT OF BRAZED SANDWICH CONSTRUCTION MATERIALS FOR HIGH TEMPERATURE APPLICATIONS. Period covered: February 15, 1956 to August 15, 1957
An investigation was undertaken to study various base metal-braze alloy combinations for honeycomb sandwich structures that would have utllity up to a maximum temperature of 1200 F. The base alloys, 17-7PH, 422, A286, 19-9DL,,and 17-14 Cu Mo were evaluated silver and nickel base brazing alloys to determine their compatability and strength characteristics to develop am optimum sandwich combination. On the basis of brazing studies and structural tests, it was found that A286 corrosion resistant steel brazed with a nickel-chromium-silicon-iron- boron alloy offered the optimum sandwich construction for operating temperatures of 1000 to 1200 F. Stutic flexure and edgewise compression data are given for all optimum base metal-braze alloy combinations. S/N curves for fiexural fatigue studies made at temperatures of 75, 500, and lOOO F are presentcd for the A286 with NiCr-Si-Fe-B optimum sandwich combination. (auth)
