عنوان انگلیسی Comparison of Plastic Anisotropy and Crystallographic Texture Evolution of Aluminum 1100 Between 90° and 135° ECAE Processes
چکیده انگلیسی مقاله A rolled sheet of aluminum 1100 was processed by two ECAE dies with inner corner angles of 90° and 135°. The samples were processed using route A up to 4 and 10 passes in ECAE 90° and 135°, 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 135° ECAE, compared to the 90° case. Studying crystallographic texture evolutions reveals that ECAE 135° is more capable than ECAE 90° in the development of cube components; however, the rate of texture evolution is slower in ECAE 135°. Dissimilar prominent texture components are also developed by two different ECAE processes.
