Studies of Nb with combined additions of interstitial and substitutional solutes show that the addition of O/sub 2/ together with Ti or Zr is- an excellent method of preparing forgeable Nb alloys with good high-temperature strength and adequate low-temperature ductility. Nb-1.5% Ti-0.50% O had triple the strength of pure Nb up to 2200 deg F and was ductile at temperatures from -76 to +2200 deg F. (D.L.C.)
