Effect of the asymmetry of the stress cycle on the corrosion fatigue resistance of 1561 aluminum alloy

Previously abstracted from original as item 9003-6.4-0076Y. Flat (6 x 20 mm) specimens of 1561 alloy were tested in pure bending at 17-20 Hz in air and sea water, with mean tensile stresses of 0, 50, 100, and 180 MPa. It is found that the effect of sea water on the nucleation of a stress corrosion c...

Description
Summary:Previously abstracted from original as item 9003-6.4-0076Y. Flat (6 x 20 mm) specimens of 1561 alloy were tested in pure bending at 17-20 Hz in air and sea water, with mean tensile stresses of 0, 50, 100, and 180 MPa. It is found that the effect of sea water on the nucleation of a stress corrosion crack in the alloy decreases with increasing stress cycle asymmetry. Under conditions of asymmetric loading, the corrosion fatigue of 1561 alloy can be predicted, at the stage of macrocrack nucleation, using the Goodman relation. Graphs. 8 ref.--X-ref.(US).
