The texture of Al – 0.7 wt. % Li alloy processed by two different methods of severe plastic deformation (SPD) has been experimentally investigated by X-ray diffraction technique, and analyzed in terms of the orientation distribution function (ODF). It was found that severe plastic deformation through both equal channel angular extrusion (ECAE) and hydrostatic extrusion (HE) results in ultrafine grained structure in Al – 0.7 wt. % Li alloy. Microstructure (grain shape and size) of the materials produced via SPD methods strongly depends on the applied technological parameters and method. The texture of investigated alloy was different in both cases due to change of deformation mode.
