“…Depending on the amount and type of alloying element, the More importantly, from the various Ti alloys used as dental or orthopedic alloys, such as Ti6Al4V, Ti6Al7Nb, Ti13Cu4.5Ni, Ti25Pd5Cr, Ti20Cr0.2Si, Ti13Nb13Zr, Ti12Mo6Zr, TiMo alloys, Ti22Nb2Cr, TiZr alloy, etc. [72,73], only some can be anodized successfully to a uniform nanostructure by electrochemical anodization. For instance, anodic nanostructures in the form of nanotubes can be grown on Ti6Al4V [74,75], Ti6Al7Nb [74,76], TiZr alloys with Zr amount in the 5-50 wt.% [77,78], Ti24Zr10Nb2Sn [79], Ti13Zr13Nb [80,81], Ti28Zr8Nb [82], TiMo alloys (6-7 wt.% Mo [83,84], 15 wt.% [84]), TiNb alloys [85,86].…”

TiO2 nanostructures and more specifically nanotubes have gained significant attention in biomedical applications, due to their controlled nanoscale topography in the sub-100 nm range, high surface area, chemical resistance, and biocompatibility. Here we review the crucial aspects related to morphology and properties of TiO2 nanotubes obtained by electrochemical anodization of titanium for the biomedical field. Following the discussion of TiO2 nanotopographical characterization, the advantages of anodic TiO2 nanotubes will be introduced, such as their high surface area controlled by the morphological parameters (diameter and length), which provides better adsorption/linkage of bioactive molecules. We further discuss the key interactions with bone-related cells including osteoblast and stem cells in in vitro cell culture conditions, thus evaluating the cell response on various nanotubular structures. In addition, the synergistic effects of electrical stimulation on cells for enhancing bone formation combining with the nanoscale environmental cues from nanotopography will be further discussed. The present review also overviews the current state of drug delivery applications using TiO2 nanotubes for increased osseointegration and discusses the advantages, drawbacks, and prospects of drug delivery applications via these anodic TiO2 nanotubes.

“…It is well known that the elastic modulus is determined by the bonding force between atoms, which is related to the crystal structure and to the distances among atoms [3][4][5]. Specially, for a multiphase alloy the elastic modulus is mainly determined by the modulus and the phase fractions of the individual phases [6][7][8]. In order to obtain an ultralow elastic modulus, great efforts have been made on phase tailoring with different strategies, e.g.…”

“…In order to obtain an ultralow elastic modulus, great efforts have been made on phase tailoring with different strategies, e.g. composition design, heat treatment and plastic deformation [4][5][6][7]9]. In addition to phase composition, it is reported that dislocation and grain boundary also have a great effect on the elastic modulus via introducing a disordered region in materials [7,[10][11][12].…”

The elastic modulus of TiNi alloy was tailored by electroplastic rolling deformation and the effects of rolling strain and electropulse duration on the elastic modulus of electroplastic rolled TiNi alloy were systematically investigated. With rolling strain increasing from 0 to 1.70, the elastic modulus decreases from 61 to 30 GPa, which can be attributed to the increase in dislocation density and deformation-induced low modulus B19′ martensite phase. With electropulse duration increasing from 80 to 120 µs, the elastic modulus first decreases due to the volume fraction increase in low modulus B19′ martensite phase and then slightly increases on account of the dynamic recovery of dislocation and reverse martensite transformation resulted from electroplastic effect induced by high-energy electropulse.

“…A good example of this is of commercial Ti and Ti-6Al-4V alloy (most common alloy) having elastic moduli of ≈105 GPa and ≈110 GPa, respectively [5,15], which surpasses human bone, the latter having elastic modulus of ≈10-30 GPa [4,16]. Low elastic modulus close to that of a bone is a desirable characteristic for Ti alloys to avoid the stress shielding effect [17]. Therefore, to attain successful implants, it becomes necessary to decrease the elastic moduli of such materials without forfeiting their supplementary properties.…”

“…One of the ways to decrease the elastic moduli of Ti-based alloys, to be close to those of natural human bone, is the formation of a β-Ti structure. In order to stabilize the composition of the β-Ti phase in Ti-based alloys, very often Ti is alloyed with relatively large amounts of Nb and Ta [12,17,18]. Also, nitrogen (N) doping in Ti-based alloys helps reduce the elastic modulus [19,20].…”

Rising demand for bone implants has led to the focus on future alternatives of alloys with better biocompatibility and mechanical strength. Thus, this research is dedicated to the synthesis and investigation of new compositions for low-alloyed Ti-based compounds, which conjoin relatively acceptable mechanical properties and low elastic moduli. In this regard, the structural and mechanical properties of α + β Ti-Fe-Cu-Sn alloys are described in the present paper. The alloys were fabricated by arc-melting and tilt-casting techniques which followed subsequent thermo-mechanical treatment aided by dual-axial forging and rolling procedures. The effect of the concentrations of the alloying elements, and other parameters, such as regimes of rolling and dual-axial forging operation, on the microstructure and mechanical properties were thoroughly investigated. The Ti94Fe1Cu1Sn4 alloy with the most promising mechanical properties was subjected to thermo-mechanical treatment. After a single rolling procedure at 750 °C, the alloy exhibited tensile strength and tensile plasticity of 1300 MPa and 6%, respectively, with an elastic modulus of 70 GPa. Such good tensile mechanical properties are explained by the optimal volume fraction balance between α and β phases and the texture alignment obtained, providing superior alternatives in comparison to pure α- titanium alloys.
