Procurement of five 15 kg heats of V-Cr-Ti alloys with variations in Cr and Ti concentrations from the primary V-4Cr-4Ti composition. Fabrication into sheet product, determination of the tensile and Charpy impact properties, and preparation of specimens for reactor irradiation experiments. Data obtained from these alloys will be used to define the allowable ranges of Cr and Ti within which consistent properties may be obtained. Four 15 kg heats with variations in Cr and Ti concentration have been procured in various plate and sheet thicknesses. Measurements of recovery and recrystallization kinetics, precipitation behavior, and Charpy impact properties are in progress to compare properties with the behavior of the primary alloy composition V-4Cr-4Ti. In the fully recrystallized condition, the impact properties of the V-6Cr-3Ti alloy are inferior to those of the 500 kg heat of V-4Cr-4Ti. However, properties comparable to those of the V-4Cr-4Ti can be obtained of the V-6Cr-3Ti as tested in a partially-recrystallized condition. 5 figs., 4 tabs.
