Anisotropy of Growth Behavior of Small Fatigue Crack in Rolled Plate of Age-Hardened Al Alloy

Anisotropy of Growth Behavior of Small Fatigue Crack in Rolled Plate of Age-Hardened Al Alloy

A rolled aluminum alloy plate has a remarkable texture. This texture affects the mechanical properties. In this study, rotating bending fatigue tests were carried out on plain specimens cut out from a rolled plate of an age-hardened aluminum alloy, 7NO1-T4, in the rolling direction (material L) and...

Zusammenfassung:A rolled aluminum alloy plate has a remarkable texture. This texture affects the mechanical properties. In this study, rotating bending fatigue tests were carried out on plain specimens cut out from a rolled plate of an age-hardened aluminum alloy, 7NO1-T4, in the rolling direction (material L) and its longtransverse direction (material T) in order to investigate the influence of the texture on the fatigue properties. Slight anisotropy of the crack growth rate is recognized. This is caused by the difference in the crack propagation mechanism, that is, the fracture mode is a tensile-type in material T and a shear-type in material L.
