Abstract
-
Eight superalloys of A-286, Elgiloy, Hastelloy B, M-252, Rene 41, Udimet 500, Udimet 700 and Waspaloy were processed to ultra fine fibers of .001 inch diameter or less and their roam temperature physical properties evaluated. All alloys except A-286 had ultimate strengths in the range of 160,000 to 220,000 psi as solution heat treated. Alloy A-286 had a tensile strength of 100,000 psi.
Multifilament yarns composed of seven (7), nineteen (19) and thirty-seven (37) filaments of Elgiloy and Rene 41 were sheathed with a Chromel-C alloy ribbon and processed to .0027 inch diameter. Tensile strengths were determined for the sheathed yarns at 1600°F., 1800°F., and 2000°F. in air and argon. The oxidation resistant Chromel-C considerably improved the 1800°F. and 2000°F. tensile strength of the Rene 41 alloy, but the effect on Elgiloy was slight.
