This paper reports on the variation of rare earth elements in the aluminum-free magnesium alloy ME21 (2 wt% Mn and 1 wt% RE) in order to investigate the sensitivity to the amount and kind of the rare earth elements regarding strength and ductility. The paper will show the results of casting experiments of some alloy variations of ME21 which contain different amounts of Cerium and Neodymium. The influence of the different alloying elements on the microstructure before and after heat treatment is shown. Furthermore, rolling trials with different schedules are conducted and the mechanical properties of the sheets are presented and discussed with respect to arising textures. The results of this casting and rolling trials are used to discuss how to tailor the mechanical properties of the magnesium alloy ME21.
