Investigation of Microstructural and Mechanical Properties of Different Titanium Alloys for Gamma Radiation Properties and Implant Applications

In this study, the advantages and disadvantages of different titanium alloys used as industrial and biomedical implant materials are evaluated within the scope of multiple parameters. This research is supported by simulations and aims to understand how titanium and titanium alloys differ mechanically, micro-structurally and in terms of radioactivity. The matrix material of the eight samples used in this research is titanium. The effects of different elements such as Al, V, Sn, Ni, Pb, Mo, Cr, Zr, Fe, Nb, Co on titanium have been examined, the results are compared by considering multiple parameters, and the superior properties of the prominent alloys are highlighted. As a result of the mechanical and electrical tests performed on the alloys, it is obvious that the titanium alloy consisting of Mo and Nb has the highest Brinell hardness, elastic modulus, tensile strength and electrical conductivity parameters compared to other alloys examined within the scope of this research. In the metallographic studies and analyses on samples made up of different alloys, different structures and images emerge for each alloy. These elements rapidly lower the solidification temperature of the material, allowing the β phase to be formed. It has been observed that the two-phase situation has positive effects on the material. On the other hand, the results of gamma ray attenuation tests reveal that Mo and Nb, which make up the alloy, have superior performance compared to other alloy samples due to their high atomic number.
