| Abstract Scope |
Implant technology is being continually advanced, as scientists and engineers pursue ways to develop new medical devices and investigate better options available for patients with cardiovascular diseases and/or orthopedic disorders. Among numerous kinds of metallic biomaterials such as stainless steel or Titanium (cp Ti), have achieved significant applications due to their outstanding mechanical properties. In past decades, metastable beta titanium alloys containing biocompatible elements (such as niobium, tantalum, zirconium, hafnium, molybdenum...) have shown several intriguing characteristics. However, β-types Ti alloys are not adapted due to their poor plastic deformation when compared to their traditional counterparts. In this study, it is investigated that by adjusting or exploiting new alloying compositions one can enhance the performance of the β-type alloys in terms of superelastic and mechanical properties. Two new classes of Ti-Hf and Ti-Zr-based alloys will be discussed. From experimental findings, important remedies for conventional β-type Ti alloys will be highlighted. |
