Strain aging studies using fioating zone-melted niobium continued. Tensile data on niobium binary and ternary alloys were obtained at room temperature and 1093 deg C. A Nb--5 wt.% Mo--5 wt.% Hf alloy, tested in air, had an ulti- mate tensile strength of 43.350 psi at 1093 deg C. Dilute Zr and Hf additions were found to significantly increase the recrystallization temperature of niobium. Workability and hardness data for niobium with binary additions of Zr, Hf, V, Mo, W, Al, Re, and Y are presented. (For preceding period see WADC-TR-57-344, Part II). (auth)
