Optimization of mechanical properties of dilute Mg-Zn-Y alloys prepared by rapid solidification

The presented work is focused on the investigation of dilute Mg-Zn-Y alloys prepared by the consolidation of rapidly solidified ribbons. Particularly, the influence of both amount of the Zn and Y alloying elements (varies between 1 and 2 at.%) and the metal flow rate during extrusion on the initial microstructure and resulting mechanical properties is discussed. The average grain size of investigated alloys varies between 700 and 1200 nm....
