Abstract : Titanium and its alloys are getting much attention due to their excellent properties particularly in biomedical applications. However, the current implant materials, i.e. cp-Ti and Ti-6Al-4V alloys exhibit higher elastic modulus than that of the human bone, thus creating a stress shielding effect which leads to implant failure. Recently, the β-type titanium offers a great potential as a future material candidate in fabricating more suitable biomaterials owing to its non-toxicity, allergy-free characteristic, and lower elastic modulus similar to that of the bone. In developing the novel β-type titanium, sufficient knowledge on the β-stabilizing elements required in producing β phase titanium is important. Therefore, the phases and properties of new titanium alloys with their β-stabilizing elements are reviewed.
