A spray-cast Al-7034 alloy was processed by equal-channel angular pressing (ECAP) to a total of 8 passes at 473 K and the pressed samples were examined using transmission electron microscopy, differential scanning calorimetry and electron back-scatter diffraction. It is shown that the grain size of the alloy is reduced to ~0.3 μm by ECAP and the high pressures associated with ECAP lead to a fra...

the full annealing aa6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ecap) and cold rolling (cr) in order torefine its microstructure and to improve its mechanical properties. according to the results of hotand cold tensile tests, the combination of ecap and cr significantly affected the final strengthand ductility of studied...

Grain refinement to the sub-micron scale was found enhance both strength and plasticity. In this size range, micro-mechanisms of deformation are not yet sufficiently specified. present work, strain rate sensitivity investigated in an Al-Mg-Si alloy processed by equal-channel angular extrusion. The microstructure controlled conventional transmission electron microscopy orientation imaging-ASTAR....
