In recent years, some magnesium alloy systems have received attention to serve as potential materials for orthopedic implants due to their biocompatibility and biodegradability. Besides acceptable mechanical strength and corrosion rate, also non- Toxicity is an important criterion in the development of these degradable magnesium alloys. Zinc and calcium are essential micro-nutrients in the body, therefore are not expected to be harmful, and positively influence strength by grain refinement and age hardening. To identity biomedical as well as other applications, the as-cast Mg-lZn-ICa (ZX11) material was tested for standard corrosion resistance as well as compression and creep strength, also at elevated temperatures. Microstructural investigations complete the determination of relevant characteristics for the use of ZX11. Grain size reduction is observed along the radius of the cylinder and SEM-EDX analysis reveals Mg2Ca and Mg6Ca2Zn3 phases have formed on the grain boundaries. Dislocation climbing seems to be the rate controlling deformation mechanism for creep. Compression strength increases with temperature gradually increased up to 100 °C, plateaus between 100 and 175 °C and decreases after that. Acceptable corrosion properties have been observed.
