  Pressing materials in ECAP angular molds is one of the forming methods and processes that is done in order to create high strains and stiffness with microstructural improvement. Using angle forming in molds with high pressure, and due to the certation of work hardening phenomena, microstructural improvement, good mechanical properties and high flexibility can be achieved. In this paper, the quality of microstructure changes and the improvement of conditions and mechanical strength using the pressing method for aluminum alloy (6xxx) in an angular form is investigated. In this way the prepared forms have two square and circular cross sections and the samples were pressed through the angular pass only one time. The results of the studies showed that by pressing the samples, the structure was improved and uniform microstructure achieved. In the meantime, the samples with a circular cross-section showed better conditions of the effects of work hardening and structural improvement. Manuscript profile
