Metallographic Characterization of a New Biomedical Titanium-Based Alloy for Orthopedic Applications

Abstract

Orthopedic biomaterials play an important role for patients, improving the quality and expectancy of life. Titanium alloys corresponding to the Ti-Nb-Zr-Ta system, composed of non-toxic elements, have attracted the attention of the researchers, because of their unique combination of properties, which make them potential candidates for medical applications in the orthopedic field. This paper is presented a new biocompatible titanium alloy, Ti-25Nb-10Zr-8Ta, which was produced from pure metals (Ti, Nb, Zr, and Ta) using the vacuum induction melting method in a levitation furnace Five Celes. The microstructure and phase composition of the titanium alloy were investigated by scanning electron microscopy (SEM) and X-Ray diffraction (XRD).
