Abstract


Cast magnesium alloy AZ31 was processed by equal channel angular pressing (ECAP); 1-8 passes were applied using different processing routes A, BC and C. Samples were cut from the extruded billet in the extrusion, transversal and normal directions. Micro-tensile tests were performed at room temperature with an initial strain rate of 1´10-3 s-1. The microstructure analysis showed a significant grain reducing. Texture of extruded samples was studied using EBSD technique. The true stress-true strain curves and characteristic stresses exhibit a pronounced anisotropy for all processing routes as a consequence of the developed different texture. © VBRI Press.
