Abstract : The study attempts to produce an alloy suitable for 3 in. plate or an 8 in thick forging possessing definite strength, stress corrosion, fracture toughness, and fatigue properties. Various quenches were used on 1 in plate to simulate quenching these products. A single composition of 6.75% Zn, 2.5% Mg, 1.2% Cu was chosen and both the minor addition elements (Zr, Cr, and Mn) and the aging practices were varied. (Author)
