Description:
In this study, we have used in-situ micro-Laue diffraction combined with micropillar compression of focused ion beam milled Al 13 Co 4 complex metallic alloy to investigate the evolution of deformation in Al 13 Co 4 . Streaking of the Laue spots shows that the onset of plastic flow occurs at stresses as low as 0.8 GPa, although macroscopic yield only becomes apparent at 2 GPa. The measured misorientations, obtained from peak splitting, enable the geometrically necessary dislocation density to be estimated as 1.1 × 10 13 m −2 .
