“…From the obtained values, it is possible to observe that the addition of molybdenum increases the microhardness value in relation to cp–Ti, which is expected, as molybdenum has greater hardness than titanium. It can be verified that the hardness value of as-cast Ti–15Mo alloy is in accordance with values published in the literature [ 5 , 6 , 23 , 24 ], and, with oxygen doping, there is a significant increase in hardness values.…”

The Ti–15Mo alloy has its mechanical properties strongly altered by heat treatments and by addition of interstitial elements, such as, oxygen, for example. In this sense, the objective of this paper is to analyze the effect of the introduction of oxygen in selected mechanical properties and the biocompatibility of Ti–15Mo alloy. The samples used in this study were prepared by arc-melting and characterized by density measurements, X-ray diffraction, scanning electron microscopy, microhardness, modulus of elasticity, and biocompatibility tests. Hardness measurements were shown to be sensitive to concentration of oxygen. The modulus results showed interstitial influence in value; this was verified under several conditions to which the samples were exposed. Cytotoxicity tests conducted in vitro showed that the various processing conditions did not alter the biocompatibility of the material.

“…Figure 3 also presents a comparison of the results obtained in this paper with previously published studies in the literature [23][24][25] , showing good agreement with them. Figure 3 also shows that the sample after hot swaging (Ti-15Mo#1) presents a hardness value higher than after melting (Ti-15Mo#0).…”

With the increase in life expectancy, biomaterials have become an increasingly important focus of research because they are used to replace parts and functions of the human body, thus contributing to improved quality of life. In the development of new biomaterials, the Ti-15Mo alloy is particularly significant. In this study, the Ti-15Mo alloy was produced using an arc-melting furnace and then characterized by density, X-ray diffraction, optical microscopy, hardness and dynamic elasticity modulus measurements, and cytotoxicity tests. The microstructure was obtained with β predominance. Microhardness, elasticity modulus, and cytotoxicity testing results showed that this material has great potential for use as biomaterial, mainly in orthopedic applications.

“…[12,13] The presence of x-phase particles significantly affects the mechanical properties and superelasticity of b-Ti alloys. [14,15] Thus far, the available literature on the superelasticity of b-Ti alloys subjected to large deformation (>5 pct) was limited. The effects of x-phase particles on the deformation mode of Ti alloys still remain unclear.…”

QIANG LI, MITSUO NIINOMI, MASAAKI NAKAI, ZHENDUO CUI, SHENGLI ZHU, and XIANJIN YANG The superelasticity and deformation behaviors of b-type TiNb 24 Zr 2 subjected to aging treatment were investigated in this study. As the aging time increased, the precipitation of isothermal x phase was found to restrain the formations of twinning and stress-induced a¢¢ martensite. The superelastic recovery of the sample first improves and then deteriorates with extended aging times. A maximum and stable superelastic recovery of 4.3 pct is obtained for an aging time of 7.2 ks.
