Abstract : An investigation was made to evaluate 7079-T652 Al alloy for use in heavy section forgings on the B-58. The yield and tensile strength exceeded Alcoa guaranteed minimums by 5 to 10% and the elongations were double or almost double. The short transverse yield and ultimate tensile strengths and elongation of a 6-in. section were similar to those of a 4-in. section, but the notch tensile strength was lower in the thicker section. The ratio of notch to standard tensile strengths averaged 0.81. The endurance limit stress for ten million was under 4,300 psi for the lug type specimens used. (Author)
