Abstract : Vanadium-niobium all ys containing reactive and refractory metal and interstitial additions were prepared as 200-gram nonconsumable-electrode arcmelted ingots. A T THE <)W/O Nb level, strengths as high as 5 ,000 psi at 2000 F were measured for a V-5w/o Ti-20w/o Nb-10w/o Ta composition; at 60w/o Nb, the strongest alloy was V-1w/o Ti60w/o Nb-2.5w/o Mo-0.5w/o Ru which had an ultimate tensile strength of 65,500 psi at 2000 F. Additions of W, Ta, or Mo generally caused reduced fabricability and ductility. Extruded bar stock and warm-rolled plate and sheet from the 100-pound consumable-electrode arc-melted ingot of V-1w/o Ti-60w/o Nb were received. Initial examination indicated that this material was free from defects. (Author)
