Evolution of crystallographic texture by hot rolling deformation at the temperature of 200°C was investigated by hot rolling tests on as-cast Al-5wt%Mg alloy fabricated by a new strip cast technology. Texture variation through the thickness direction in the Al-5wt%Mg alloy was examined experimentally. Macrotexture and microtexture measurements were conducted using X-ray diffractometer and electron backscatter diffraction (EBSD), respectively. Experimental investigation reveals that the evolution of texture and microstructure is strongly dependent on a distance from center of the Al-5wt%Mg alloy sheet. It was found that the shear texture components tend to be increased at the surface region of the hot-rolled specimen.
