β-type Ti Alloys for Biomedical Applications

Abstract

In the world market, medical products emerge as a sector that directly concerns people’s life quality and related activities. The medical product industry continues to grow rapidly in the world, especially in developed countries in line with the advances in technology, along with the elderly population and welfare level. In this context, biomedical implants constitute an important branch of the medical product industry. Among the materials preferred for implant production, the metallic biomaterials are very popular due to their superior mechanical properties. Ti and Ti alloys, among the metallic biomaterials, draw more attention considerably compared to stainless steel and Co-Cr alloys due to their characteristic features such as high specific strength and superior corrosion resistance, low density and low modulus of elasticity. Although the elastic modulus of titanium and its alloys is low compared to the other metallic biomaterials, it remains higher than bone. β-type Ti alloys have been developed to prevent the stress shielding effect caused by the elastic modulus mismatch and sterilization of the biomaterials used in the body from toxic alloy elements. In this article, the effect of the use of β-type Ti alloys, which are extremely prospective materials and open to development, in the body on host organisms, and the efficiency of the developed alloys have been investigated.
