“…2(c), dentritic 335 structure was clearly observable. 336 The XRD patterns of the TNZ alloys are given in [62]; however, in that study [62], the Nb level was kept constant [68], grain size, or solid-solution strengthening effects [69]. 381 Similarly, it can be observed that the microhardness levels of the 382 alloys present the same ranking order (Fig.…”

“…Resorption in bone tissue can occur when it 67 carries lower amounts of biological load due to a rigid implant 68 material carrying most of the loads [7]. In such cases, the implant 69 material may loosen [6]. The fact that titanium (Ti) alloys have a 70 lower Young's modulus in comparison with 316L stainless steel 71 and Co-Cr alloys is an important factor in their increasing use as 82 reported.…”

“…As well as Ti, Zr and Mo can present good mechanical and corrosion strength, in addition to high biocompatibility. Thus, the development of Ti-Zr-Mo system alloys combined novel β-type Ti alloys with low Young's modulus 11,12 . In our preliminary studies, the Ti-15Zr-15Mo alloys showed good quality for use as implantable materials, because they presented better combination of microhardness and Young's modulus than Ti-6Al-4V and CP-Ti [13][14][15] , tribocorrosion resistance superior than CP-Ti 16 , and cytotoxicity similar to CP-Ti-cp 15,17 .…”

Titanium (Ti) is employed as a biomaterial because of its superior biocompatibility and favorable mechanical properties that can be changed with the addition of alloying elements, such as zirconium and molybdenum. Silver is an alloying element recognized for its antibacterial action, which can improve the mechanical strength and decrease Young’s modulus of Ti. This work studies the effect of silver addition (1 and 3 wt%) on the crystalline structure, microstructure, Vickers microhardness and Young’s modulus of Ti-15Zr-15Mo (wt%) alloy, targeting for a potential application as a biofunctional material. The ingots were produced by argon arc melting and subsequently subjected to a heat treatment of homogenization, hot-rolling and solubilization heat treatment. Chemical composition indicated good quality on the processing of the alloy. Crystalline structure and microstructure analyzed by X-ray diffraction, optical microscopy and scanning electron microscopy showed only titanium’s β phase. Finally, mechanical properties studied by Vickers microhardness and Young’s modulus measurements presented that the addition of low content of silver did not significantly modify the alloy’s mechanical properties, but it can include antibacterial properties on the bulk.

“…However, to date, reports of the application of Zr alloys in the replacement of biological hard tissues are still very rare. The microstructure and magnetic susceptibility of Zr-Mo alloys as cast have been studied and it was found that Zr alloys are useful for medical devices that use Magnetic Resonance Imaging (MRI) [3,12].…”

CORROSION BEHAVIOR OF Zr-10Mo ALLOYS IN NIOBIUM-DOPED LACTATE RINGER'S SOLUTION. This research discusses the corrosion behavior of Zr-10Mo alloys in Niobium-doped lactate ringer's solution. The addition of Niobium of 1%, 3% and 5% on Zr-10Mo alloys aims to study the effect of adding Niobium to the hardness, microstructure and corrosion resistance of Zr-Mo alloys. The alloys are made by melting the materials of Zr, Mo and Nb with a certain percentage of weight using single arc melting furnace in Argon atmosphere with high purity and Tungsten eletrodes. The alloys (as cast) are subjected to hardness testing using C-scale rockwell, microstructure using optical microscopy, compounds and phases in the alloys (as cast) using XRD and corrosion testing using polarization method in lactate ringers' solution. The hardness value increases by the addition of Niobium, Zr-10Mo-1Nb alloy of 34 HRC, Zr-10Mo-3Nb alloy of 38 HRC and Zr-10Mo-5Nb alloy of 41.5 HRC. The basketweave-shaped microstructure with the addition of Niobium creates relatively smaller grain size. The value of corrosion rate decrases by the addition of Niobium at the immersion times of 0 minute, 60 minutes and 120 minutes, Zr-10Mo-1Nb alloy of 4.208 mpy, Zr-10Mo-3Nb alloy of 3.538 mpy and Zr-10Mo-5Nb alloy of 2.813 mpy, included in the excellent category (1-5 mpy).
