This paper presents how the mechanical properties, microstructure and degradation rate of extruded Mn-containing Mg-Gd alloys can be modified during extrusion. Gd as a rare earth element is particularly interesting due to influence on texture development in Mg, therefore studied base alloy system. The contents were investigated between 2 9 wt.%, with Mn additions 0.5 1.0 wt.%. grain sizes corre...
