DESIGN DATA STUDY FOR COATED COLUMBIUM ALLOYS. Final Summary Technical Report, December 21, 1961 through December 21, 1962

Technical Report ·
OSTI ID:4746047
Design data properties were determined for two protective-coating -- niobium-alloy systems involving Pfaudler and TRW oxidation protective coatings on Fansteel-85 niobium alloy up to temperatures of 2600 deg F. Prior to the design data study, preliminary screening oxidation, bend and prestrain tests were conducted on seven oxidation protective coatings applied to D-14 and FS-85 niobium alloys. Based on the screening test resuits, Pfaudler and TRW coatings were selected for the mechanical properties evaluation. The following design properties were determined for uncoated and Pfaudler and TRW coated 30 mil FS-85 alloy sheet: coating cyclic oxidation protective life, tensile properties of uncoated (in vacuum) and coated (in air) sheet, coating deformation tolerance, and stress rupture properties of coated sheet (in air).
