The main orientations in this alloy are the cubic {001}100, nearcubic {210}001 textures, the rolling {112}111 and S-{123}634 textures and the orientation {011}112. The paper shows that changes in the rolling and heat treatment modes lead to different combinations of the mentioned grain orientations and consequently to variant anisotropic properties. The new technological parameters of 8011A sheet production have been developed to eliminate earing during drawing.</p>Drawingearinganisotropytexture parameterslateral strain coefficientscrystallographic orientationrollingrecrystallization annealingearing indexgrain orientation distribution functionpole figuresВытяжкафестонообразованиеанизотропияпараметры текстурыкоэффициенты поперечной деформациикристаллографическая ориентировкапрокаткарекристаллизационный отжигпоказатель фестонообразованияфункция распределения зерен по ориентациям
