Variation of Extrusion Process Parameter for the Magnesium Alloy ME21

Abstract

Extrusion is an economic production process for the generation of semi-finished magnesium products that can be used for biomedical and automotive applications. This paper reports on the variation of process parameters (temperature and extrusion speed) in the aluminum-free magnesium alloy ME21 (Mg–2Mn–0, 6Ce–0,3) during extrusion in order to investigate their influence on strength and ductility of the produced profiles. The influence of the varied process parameters on the microstructure before and after heat treatment is shown. Furthermore, the mechanical properties of the extruded profiles are presented and discussed with respect to arising textures. The results of this work are used to discuss how to tailor the mechanical properties of the magnesium alloy ME21 during the extrusion process.
