| Abstract Scope |
In this paper, three wrought magnesium alloys with texture and microstructure modifying elements, binary M2 and the alloyed counterparts with Ca (MX21) and RE (ME21) were extruded under similar conditions. The development of microstructure and texture in extrusion differs significantly from that in magnesium rolling. Any improvement in the properties of extrusion alloys requires a better understanding of the effects of alloying elements and processing parameters and how they determine the final microstructure of flat products. Therefore, the influence on the mechanical properties and the forming behaviour (Erichsen values IE) with relation to microstructure, texture and strain rate sensitivity is presented and discussed in this paper. It can be shown that, depending on the alloying elements, there is a clear difference in texture development and strain rate sensitivity. In addition, not only the texture, but also the microstructure has a great influence on formability. |
