Abstract

On the basis of theoretical and experimental studies the complex influence of process conditions such as the geometric characteristics of the billet and the tool were investigated regarding the extrusion of bimetallic rods and tubes. As a core material magnesium alloys of the Mg-Al-Zn system and as shell materials aluminum and its alloys of the Al-Mg-Si and Al-Zn-Mg were extruded. An increase in the strength properties of the aluminum alloy shell—compared to the core of a magnesium alloy—increases the inhomogeneity of the speed distribution of the metal flow resulting in defects. A sustainable processing can be established by the extrusion of bimetallic rods which consist of an Mg-Al-Zn-Mn core and an Al-Mg-Si shell.
