are explored to replace diseased bones [1-3]. In particular, metallic implant materials, e.g. SUS316L stainless steel, Co-Cr-Mo type alloys, Ti and Ti alloys (e.g. Ti-6Al-4V) are widely used as orthopaedic and dental implant materials. Among these, Ti and some of Ti alloys are preferred load-bearing implant materials due to their relatively low modulus, excellent strength-to-weight ratio, good......
