Abstract : A por/ion of the Design Data Study mechanical property tests on Pfaudler and TRW coated 30 mil B-66 and D-43 niobium alloy sheet has been completed. Data are presented from one atmosphere cyclic oxidation tests at 1600, 2300 and 2600 F. These data are compared with the results of tests conducted in the preliminary evaluation phase of the program. Tensile data for both uncoated and coated sheet are reported for the temperature range room temperature to 2300 F. The tensile behavior of coated B-66 and D-43 alloy sheet is discussed relative to the behavior of uncoated sheet. Preliminary results of creep tests is air conducted on coated B-66 and D-43 alloy sheet are presented. Tests have been conducted at 2000 and 2300 F. A few generalized statements of the creep behavior of these coated alloys are presented. (Author)
