Abstract

The double ligament tensile (DLT) test was used to evaluate the tensile properties and anisotropy of a lithium-containing aluminum alloy in the three orthogonal directions of the wrought ingot metallurgical plate. In order to minimize uncertainties associated with results obtained from this test comparisons are made with results obtained from the conventional tensile test. Variation in tensile properties with direction of stressing are discussed in terms of the specific role of specimen size and configuration, and intrinsic microstructural features.
