Abstract : Room-temperature tensile properties were determined for large 7075-T6 and 7075-T73 aluminum-alloy forgings. Forging sizes ranged from about 1.5 to 15 inches (short-transverse direction) for production forgings and up to 20 inches for step forgings. Heat-treated thickness was 0.75 to 1.000 inch for the T6 temper but ranged up to 10 inches for the T73 temper. Regression coefficients and standard d deviations are presented for three properties (TUS, TYS, and elongation) in each of three test directions. In addition, average values and two statistical minima are tabulated for each property and test direction at each of several discrete sizes, and a comparison is made with the corresponding requirements of Specification MIL-A-22771C(ASG).
