The major part of the Design Data Study mechanical property tests on Pfaudler and TRW coated 30 mil B-66 and D-43 niobium alloy sheet was completed. The results of tensile tests conducted on coated sheet in the temperature range room temperature to 2600 F are reported and compared with properties of uncoated sheet. A limited study of the effect of different tensile strain rates in the 2300 to 2600 F temperature range is discussed. Results of creep tests conducted on the coated B-66 and D-43 alloy sheet are reported. These data pertain to tests run at 1600, 2000, 2300 and 2600 F in air. Preliminary results of coating deformation tolerance tests at room temperature, 400 and 800 F are presented. Author
