Metallurgical properties of twelve alpha-gamma uranium alloys based on the composition U-Mo-Cb-V-Ti alloying elements varied from 18 to 4-12 weight percent, including the corrosion resistance of three of these alloys, were determined for various heat treatments and related to the metallographic structure after heat treatment. In general, tensile ductility and impact energy were increased at constant tensile strength levels for material extruded, solutionized, and isothermally transformed rather than extruded and aged. Grain size was considerably enlarged and chemical homogeneity improved by the solutionized heat treatment. The properties of these alloys were compared with the U-2Mo-2Cb-2Zr-12Ti alloy developed previously. Substituting vanadium for zirconium raised the ductility and lowered the strength of these alloys. Corrosion resistance in boiling water at atmospheric pressure was improved by replacing zirconium with vanadium. Author
