Process and alloy development for hydrostatic extrusion of magnesium: The European Community research project MAGNEXTRUSCO

摘要

While magnesium cast products have achieved a breakthrough into industrial lightweight applications, the development is now focussing on wrought products. This leads to a broader variety of shapes as well as to improved material properties of magnesium alloys. In particular, extrusion as a shaping technology offers the possibility to produce such products. While the technology for processing magnesium alloys is available today, the industrial use is not well established because of the technical and economical limitations of both the direct, and indirect, extrusion processes. The European Commission research project, MAGNEXTRUSCO, has been implemented in order to overcome these limitations in the production of magnesium wrought components by using the hydrostatic extrusion process. This paper gives an overview of the project regarding the motivation, the objectives, and the partnership. Results with respect to micro-structural evolution of magnesium alloys, and mechanical properties due to the settings of the extrusion parameters, are presented and discussed.
