Abstract:
The tensile properties, plane-strain fracture toughness, axial-stress fatigue properties and fatigue-crack propagation rates, and the resistance to exfoliation and stress-corrosion cracking, were determined for several aluminum alloys. Two thicknesses of X7080-T7E41(T751) and 7178-T651 plate, and two thicknesses of 7075-T6510, 7075-T73510, X7080-T7E42(T7510) and 7178-T6510 extruded shapes, were evaluated.
