Evolution of Texture and Grain Size during Equal Channel Angular Extrusion of Pure Copper and 6012 Aluminum
Among different SPD techniques, Equal channel Angular Pressing has attracted the most attentions, because of applying large strain to solid bulk materials. In this research, ECAP process up to 6 passes was carried out on a pure copper and a 6012 Al-Mg-Si alloy with BC route in ECAP dies with Φ=120 and Ψ=20 and diameter of 20and 10 millimeter respectively. Moreover, X-ray diffraction (XRD) syste...

متن کاملEvolution of microstructure and texture during recovery and recrystallization in heavily rolled aluminum
The annealing behavior of nanostructured aluminum AA1050 prepared by cold rolling to an ultrahigh strain (vM = 6.4) has been investigated using both transmission electron microscopy and electron backscatter diffraction techniques, paying particular attention to changes in microstructure and texture during recovery and their influence on subsequent recrystallization. It is found that coarsening...
متن کاملRecrystallization and Texture Development in Hot Rolled 1050 Aluminum
The evolution of texture as a function of recrystallization has been characterized for hotrolled AA1050. Samples prepared from hot rolled sheet were annealed isothermally for sufficient time to allow complete recrystallization. The microstructural variation and texture evolution in the samples was observed by automatic indexing of Electron Back Scatter Diffraction (EBSD) patterns in a Scanning ...
متن کاملThe Effect of Hot Deformation Parameters on Grain Size Refinement in a Martensitic Stainless Steel
The grain size refinement of AISI 422 martensitic stainless steel in the temperature range of 950-1150 ºC was investigated by hot deformation tests. The deformed specimens were held at deformation temperature with delay times of 5 to 300s after achieving a strain of 0.3. The austenite grains exhibit a considerable growth at temperature higher than 1050˚C, while the grain coarsening is negligibl...
