“…The statuses of cells in proliferation, adherence, and migration are the primary factors affecting implant suitability and operation success rate (Giavaresi et al, ). Introducing specific textures to titanium alloy implant surface is helpful to improve the surface property which influences its biological functions (Balazic, Kopac, Jackson, & Ahmed, ; Fu et al, ; Lavenus et al, ; Manivasagam, Singh, Rajamanickam, & Gogia, ; Nunes et al, ). Plenty of studies indicate that both microstructure and nanostructure significantly influence surface properties, such as wettability (Chen et al, ; Ferraris, Bobbio, Miola, & Spriano, ; Rupp et al, ), biocompatibility (Ferraris et al, ; Zhang et al, ), surface roughness (Dul, Jonas, & Handke, ; Rupp et al, ).…”

Introducing specific textures to titanium alloy implant surface is helpful to modify the surface properties of materials. In this article, biomedical TC4 (Ti‐6Al‐4V) alloy was textured by a 10‐ps infrared laser. Laser parameters that directly affected the detailed dimension of textures and its characteristics were optimized within laser power, defocusing amount, and scanning parameters via response surface methodology. These textures consisted of groove array about 30–90 μm in depth and 100 μm in width were prepared and their surface property (including surface morphology, element composition, wetting behavior, and biocompatibility) was analyzed. Surface characteristic analysis indicated that picosecond laser texturing improved surface properties and biocompatibility mainly by altering the microstructure and morphology of materials. In addition, laser textured groove array promoted contact area and hydrophobicity of material surface. Cell culture experiments and animal studies showed that titanium alloy implants with 30‐ and 60‐μm‐deep groove arrays on the surface‐enhanced cell proliferation and adhesion. Meanwhile, compared to the polished samples, these groove arrays promoted the growth of new blood vessels and enhanced the combination of blood vessel and implants in vivo. That is, the deeper groove array was, and the better vascularizing effect the blood vessel exhibited.

“…Therefore, the majority of newly developed Ti‐based biomaterials are β alloys . In particular, metastable β Ti alloys with nontoxic elements such as Mo, Nb, Ta, Zr, and Sn and much lower modulus have been developed over recent years . Compared with Ti‐64, such metastable β Ti alloys show excellent corrosion resistance in human body fluids, lower Young's modulus, better toughness, as well as high strength.…”

Properties of Powder Metallurgy‐Fabricated Oxygen‐Containing Beta Ti–Nb–Mo–Sn–Fe Alloys for Biomedical Applications

et al. 2019

The influence of minor oxygen additions on the microstructure and mechanical properties of powder metallurgy (PM) fabricated Ti–25Nb–5Mo–3Sn–2Fe alloy is studied. The results demonstrate the positive influence of a certain oxygen content (0.35 wt%) on the microstructure and mechanical properties of sintered samples. Despite the presence of 7.0% porosity in the PM‐fabricated samples of Ti–25Nb–5Mo–3Sn–2Fe–0.35O, a high strength of 682 MPa, elongation of 7.2%, and Young's modulus of 74 GPa are obtained. The strength‐to‐modulus ratio of this alloy is higher than most common Ti biomedical alloys, indicating that this alloy may have better suitability for orthopedic applications. Deviation in the oxygen content of the alloy from 0.35 wt% negatively impacts on the ductility of the samples.

“…Metastable β-type titanium-niobium (Ti-Nb)-based alloys are widely developed for application in biomedical [1][2][3] and automobiles [4,5] since the alloys exhibit low Young's modulus (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40) [1,4,6] and an optimal combination of strength (more than 500 MPa roughly) and ductility (more than 15%) [6,7]. The β phase in Ti-Nb-based alloys corresponds to a body-centered cubic (bcc) structure, and its space group corresponds to Im-3m [8].…”

In this study, the mechanism of {332}<113> twinning formation in cold-rolled Ti-35Nb-2Ta-3Zr-O (wt %) alloy was investigated based on the Taylor-Bishop-Hill theory. The experimental data of crystal orientation in the rolling bite zone was obtained via electron back-scattered diffraction (EBSD). The deformation energy of {332}<113> twinning in the propagation stage was calculated using data from EBSD in terms of the Hall-Petch-type relation. The calculation results revealed that the mechanism of {332}<113> twinning formation in β-type Ti-35Nb-2Ta-3Zr-O (wt %) alloy contained two valid models, namely the shear-shuffle model and α″-assisted twinning model. This can help to clarify the mechanism of {332}<113> twinning formation further.
