Titanium and its alloys have been used as implant materials in dental and orthopaedic applications owing to their excellent mechanical properties and corrosion resistance. However, the lack of bioactivity remains a problem. Magnesium has potential to be biomaterial because of its degradability in vivo environment and good bioactivity, the unfortunate complication is that magnesium corrodes too quickly in human bodies. To combinate the respective advantages of titanium and magnesium, a new Ti-Mg alloy for bo...
