The effect of microstructural modification on the degradation behavior and mechanical properties of Mg–5wt%Ca alloy was investigated to tailor the load bearing orthopedic biodegradable implant material. The eutectic Mg/Mg2Ca phase precipitated in the as-cast Mg–5wt%Ca alloy generated a well-connecte...
