FRACTURE TOUGHNESS, FATIGUE AND CORROSION CHARACTERISTICS OF HIGH STRENGTH ALUMINUM EXTRUSIONS AND PLATE

Abstract

All the material for the program, including 1/2-in. and 1-3/8-in. thick 7178-T651 and X7080-T7E41 plate and 11/16-in. and 3-1/2-in. thick 7075- T6510, 7075-T73510, 7178-T6510, and X7080-W510 and W511 extrusions, has been received. The compositions and tensile properties of the X7080 and 7178 plate were determined and indicate that these samples are suitable for use on the contract effort; fracture toughness, fatigue and corrosion specimens are being prepared. Following an aging study, the X7080 extrusions will be aged to the T75-type temper, and the evaluation of all the extrusions will get under way.
