Abstract

Ti-base alloys containing major amounts of Nb and Al are being studied with the object of developing new high-temperature alloys of low density. Results of the second year of this program, derived from the preparation and examination of (1) 35 quaternary alloys containing small additions of Sn, Hf, or Zr; (2) four high-purity ternary alloys; and (3) ten-pound melts of Ti15Nb-10Al and Ti-17.5Nb-15Al are discussed. In a number of alloys, improved tensile properties and oxidation resistance resulted from the addition of Sn, Hf or Zr, and in some instances very high strength-density ratios were maintained up to 1800 F. The properties of high-purity alloys were similar to those of alloys prepared with sponge Ti. It is recommended that further effort be directed toward the more highly alloyed compositions, including those containing Hf and Zr.
