HIGH-TEMPERATURE OXIDATION PROTECTIVE COATINGS FOR VANADIUM-BASE ALLOYS.
Abstract
Primary experimental effort has been on determining the influence of the coating process on the ductile-to-brittle transition behavior of coated V-60Nb-1Ti sheet. Eleven tensile samples of V-60Nb-1Ti sheet were coated in two separate pack runs under similar conditions. Several of these were tested at 32 F, 140 F and room temperature, in the as-coated condition. In addition, specimens were vacuum annealed and oxidized after coating and subsequently tested at room temperature. For specimens tested in the as-coated condition, brittle failure occurs at both 32 F and room temperature. At 140 F the material is ductile, having tensile properties similar to the uncoated, annealed alloy at room temperature. It appears, therefore, that for tensile testing a brittle-to-ductile transition occurs at just above room temperature. (Author)
