A rolled sheet of aluminum ۱۱۰۰ was processed by two ECAE dies with inner corner angles of ۹۰° and ۱۳۵°. The samples were processed using route A up to ۴ and ۱۰ passes in ECAE ۹۰° and ۱۳۵°, respectively. The mechanical behaviors of initial and processed materials were evaluated by nano-indentation and compression tests carried out at three different orthogonal directions, at room temperature. Crystallographic texture evolution during two different ECAE processes has been also studied. A considerable reduction in mechanical anisotropy is displayed for processed materials compared to the initial material by nano-indentation tests. Though there is appreciable progress in mechanical isotropy for processed materials by ۱۳۵° ECAE, compared to the ۹۰° case. Studying crystallographic texture evolutions reveals that ECAE ۱۳۵° is more capable than ECAE ۹۰° in the development of cube components; however, the rate of texture evolution is slower in ECAE ۱۳۵°. Dissimilar prominent texture components are also developed by two different ECAE processes.
