“…According to Xue et al [152], the Ti19Zr10Nb1Fe alloy shows greater hemocompatibility as compared to the Ni-Ti alloy but equivalent cytocompatibility. The absence of harmful alloying components is the cause of the better biocompatibility of β-type Ti alloys [153]. There is an immediate need for more study of β-type titanium alloys.…”

Titanium and its alloys have already been widely used as implant materials due to their outstanding mechanical characteristics and biocompatibility. Notwithstanding this, researchers and businesses alike have continued to actively pursue superior alloys since there are still problems which need urgent consideration. One of these is a noteworthy difference in the implant material’s elastics modulus and that of natural bone, which result into an issue of stress shielding. With prolonged use Ti alloys releases dangerous ions. The Ti alloy surface has a low bioactivity, which prolongs the healing process. β-Ti alloys could be used as viable alternatives when creating dental implants. Additionally, β-Ti alloys characteristics, such as low Young modulus, increased strength, appropriate biocompatibility, and strong abrasion and corrosion resistance, serve as the necessary evidence. Ti alloys when altered structurally, chemically, and by thermomechanical treatment thereby enabling the creation of material which can match the requirements of a various clinical practise scenarios. Additional research is needed which can focused on identifying next century Ti alloys consisting of some more compatible phase and transforming the Ti alloys surface from intrinsically bioinert to bioactive to prevent different issues. In order to give scientific support for adopting β-Ti-based alloys as an alternative to cpTi, this paper evaluates the information currently available on the chemical, mechanical, biological, and electrochemical properties of key β-titanium alloys designed from the past few years. This article is also focusing on β-titanium alloy, its properties and performance over other type of titanium alloy such as α titanium alloys. However, in-vivo research is needed to evaluate novel β titanium alloys to support their use as cpTi alternatives.

“…Additionally, changes in alloy characteristics such as ductility, plasticity, or formability result from differences in the relative quantities of different phases. These metallographic transformations and the properties of titanium alloys can be improved by the addition of α-stabilizers (C, N, O, Al), which increase the allotropic transformation temperature, β-stabilizers (V, Nb, Mo, Ta, Fe, Mn, Cr, Co, W, Ni, Cu, Si), which decrease the allotropic transformation temperature and the α / β ratio is affected, leading to an increase in the amount of β phase and finally neutral stabilizers (Zr, Sn, Hf, Ge, Th) [ 2 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

The mechanical properties and electrochemical behavior of two new titanium alloys, Ti20Mo7Zr and Ti20Mo7Zr0.5Si, are investigated in this paper. The alloys have been manufactured by vacuum arc remelting (VAR) technique and studied to determine their microstructure, corrosion behavior, and mechanical properties. Metallographic observations and quantitative microanalysis by optical microscopy, scanning electron microscopy SEM, and energy dispersive X-rays spectroscopy EDX were performed. Data about the three-point bending test and microhardness are presented. For electrochemical properties, three different environments were used: Ringer solution at 25 °C, Ringer solution at 40 °C simulating fever condition, and 3.5% NaCl solution. Metallographic investigation revealed the biphasic and dendritic structure of both samples when the procedures were performed. Electrochemical testing in body simulation fluid, fever conditions, and saline medium showed that the lower the proportion of silicon in the samples, the higher the corrosion resistance. The formation of a titanium oxide layer on the surface of both samples was noticed using quantitative EDX analysis. The three-point bending test for the two samples revealed that the presence of silicon decreases the modulus of elasticity; the surface of the samples displayed soft and hard phases in the microhardness test. Electrochemical impedance spectroscopy (EIS) measurements were carried out at different potentials, and the obtained spectra exhibit a two-time constant system, attesting double-layer passive film on the samples.

“…Additionally, these elements are known to reduce the conversion temperature. Compared to the other alloying elements, Nb (group V B) is known as a biocompatible stabilizing element 24–29 . In contrast to the α and β, another unwanted phase, that is, embrittling ω phase, may appear during the processing of Ti‐alloy.…”

Titanium (Ti) being a lightweight, biocompatible, and strong metal, immense attention is being paid to develop Ti-based different low-cost and efficient biomedical implants by employing additive manufacturing (AM) or 3D printing.Binder having abundant binding efficacy binds the alloying metal powders and maintains their stoichiometry and close attachment. However, in the case of Ti-alloy, the Ti, or other alloying metals, e.g., zirconium (Zr), because of their high reactivity with ambient moisture and oxygen, needs to be stabilized before the alloy formation. In this work, instead of using various nonbiocompatible thermoplastic and semi-crystalline polymers responsible for causing stress-induced defects in the final structure, the efficacy of a biocompatible amorphous polymer (i.e., polyvinyl pyrrolidone [PVP]) as a binder towards developing the Ti-alloy has been examined. PVP-bound alloying metal powders were found to be stable for 30 days (as per the XRD analysis) and exhibited a nearly similar composition to the experimental formula. Thermal debinding was examined for two temperatures, 600 and 1000 C, and compared with the help of SEM and XRD analyses. The better debinding (i.e., reduction of carbon content as per the EDX analysis) was found for the 1000 C debinding temperature.
