Abstract
Al-Li alloys in unrecrystallized conditions present a stong texture which influences considerably their mechanical behavior. The Vector Method has been chosen to analyse the texture of Al-Li alloys produced by CEGEDUR-PECHINEY. We first explain why we chose an analysis with a single incomplete {220} pole figure in reflection (maximal tilt angle = 80 degrees). The spectrum of the texture vector is drawn after re-numbering the components to make the orthotropy obvious. We then present some characteristic textures measured during the schedule of thermomechanical treatment applied to an Al-Li alloy in order to obtain sheets.
