چکیده
|
A rolled sheet of aluminum 1100 was processed by two ECAE dies with inner corner angles of 90̊ and 135̊. 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.
