Nondestructive Three-Dimensional Microtexture/Strain Quantification in Al-Li 2090
Abstract
Micro- and meso-textures" roles in defining fatigue crack path in Al-Li 2090 T8E41 compact tension samples was the central focus of the research. Near-single crystal volumes up to 0.4 mm x 1 mm x 2 mm, i. e. stacks of five or more adajacent, pancake-shaped grains, comprise over 40 vols of the center portions of 2090 plates; two other Al alloys showed little to near-single crystal volumes. The synchrotron microbeam diffraction techniques (polychromatic x-radiation) developed in this research were also found to be useful in heavily-deformed copper and Ti-6Al-4V samples.
