Magnesium alloys are utilized in the aviation and automotive industry for their low density and good mechanical properties. Magnesium alloys are also interesting for use in the field of biodegradable implants because magnesium is biocompatible element essential for human body. There exist high demands on the mechanical and corrosion properties for both applications. Those properties can be strongly affected by alloying and production method. Alloying elements can improve mechanical properties by strengthening by intermetallic phases. Further improvement can be achieved by grain refinement, which can be obtained by alloying with Zr or by hot deformation associated with the recrystallization process. Present paper is focused on characterization of Mg-2Y-1Zn alloy, which has excellent mechanical and corrosion properties. The Mg-2Y-1Zn alloy is prepared by hot extrusion. Microstructure and mechanical properties are evaluated and compared with material prepared by conventional casting. High values of ultimate and yield strengths were measured, however at the cost of low ductility.Keywords: Magnesium, extrusion, mechanical properties, grain size
