Abstract

Equal Channel Angular Processing (ECAP) was used to refine the microstructures of three lightweight structural materials: Mg-alloy ZK 60, Al-alloy 6061 and an Al-matrix-composite of 6061 Al reinforced with 10% Al₂O₃ particles. In order to investigate the impact of severe plastic deformation during ECAP upon the microstructures, both optical microscopy and the X-ray diffraction technique were employed to determine the alloy's grain sizes, elastic microstrains, and crystallographic texture. It was found that in addition to significant grain refinement, specific deformation texture and elastic microstrains were developed due to ECAP. This evolution of microstructural characteristics was discussed with reference to the deformation history. Tensile testing revealed that the effect of ECAP on ductility and ultimate tensile strength after ECAP is distinct for each type of alloy.
