Study of large strain deformation of dilute solid solutions of Al-Cu using channel-die compression

The mechanical properties of pure aluminium, Al-0.2 wt.% Cu and Al-0.4 wt.% Cu at large strains were studied using channel-die compression at three different temperatures: 77, 200 and 295 K. The evolution of the structure was studied by various techniques, including slip line studies, global texture measurements, back scattered electron Kikuchi patterns and TEM. Intense shear banding was observed at large strains and is related to the texture …
