Recently magnesium has attracted much attention as biodegradable materials. For application to various medical devices, it is important to provide required mechanical properties and biodegradability to magnesium. To develop such a material, alloying is an effective way as there are many reports about biodegradable magnesium alloys. Especially we focused on the alloy bearing essential elements because of excellent biocompatibility after implantation. In this research, the effect of alloying magnesium with zinc on mechanical properties and biodegradability was clarified. For the solid solution Mg-Zn alloy, yield strength was affected by grain size rather than solute concentration. In contrast, degradability was dependent on not grain size but additive amount of zinc. As a result, a fine-grained Mg-Zn with a suitable solute concentration possesses intended mechanical properties and biodegradation rate.
