dc.description.abstract Magnesium alloys based on Mg Al Zn system are very attractive materials in many industries due to their speci c properties. One of common forming manners suitable for this kind of material is the application of severe plastic deformation method. This paper is focused on the deformation behavior of AZ63 alloy at equal channel angular pressing process in the temperature range of 250 320◦C. For this purpose nite element analysis was used. Main attention was devoted to the in uence of processing parameters on the material ow. Among other, changes of the ow during equal channel angular pressing in chosen regions of the pressed samples were monitored. As variables, temperature, friction coe cient, strain rate, φ-angle or back pressure application were chosen. The comparison of the material ow lines at di erent conditions shows the a ecting of material ow. There are obvious considerable di erences 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 coe cient μ = 0.04, the value of the angle was = 26.5◦. cs
