Description	Magnesium alloys based on Mg-Al-Zn system are very attractive materials in many industries due to their specific properties. One of common forming manners suitable for this kind of material is the application of SPD (severe plastic deformation) method. This paper is focused on the deformation behavior of AZ 63 alloy at ECAP (equal channel angular pressing) process in the temperature range of 250-320°C. For this purpose FEA (finite element analysis) was used. Main attention was devoted to the influence of processing parameters on the material flow. Among other, changes of the flow during ECAP in chosen regions of the pressed samples were monitored. As variables, temperature, friction coefficient, strain rate, angle between individual channels or back pressure application were chosen. The comparison of the material flow lines at different conditions shows the affecting of material flow. There are obvious considerable differences between regions adjacent to the inner radius and those adjacent to the outer radius. For example in the case μ = 0 the dead zone is delimited by the angle 36°, while in the case of friction given by the coefficient μ = 0.04, the value of the angle was 26.5°.
