“…Therefore, to study the shape memory behavior of Ti-Nb alloy, the mass percentage of Nb element should be less than 34 mass%; to obtain a relatively stable β-type phase content, the mass percentage of Nb content is generally greater than 34 mass% [6]. In ternary Ti-Nb-Sn alloys, the addition of Sn can adjust the mass percentage of Ti and Nb, and then adjust the content of martensite, allow the study of the shape memory behavior and/or superelasticity of different components, and the mechanical properties of β-type Ti-Nb-Sn alloys [31,[33][34][35]. Wang [30] reported that in ternary Ti-Nb-Sn alloys, the content of martensite decreases with the increase of Sn content, and decreases with the decrease of corresponding Ti content, indicating that stable β-type Ti-Nb-Sn alloys can be obtained by adjusting the Ti and Sn contents.…”

The microstructural and mechanical properties of β-type Ti85-xNb10+xSn5 (x = 0, 3, 6, 10 at.%) alloys with low elastic modulus were investigated. The experimental results show that the Ti85Nb10Sn5 and Ti75Nb20Sn5 alloys are composed of simple α and β phases, respectively; the Ti82Nb13Sn5 and Ti79Nb16Sn5 alloys are composed of β and α″ phases. The content of martensite phase decreases with the increase of Nb content. The Ti82Nb13Sn5 and Ti79Nb16Sn5 alloys show an inverse martensitic phase transition during heating. The Ti85Nb10Sn5 and Ti82Nb13Sn5 alloys with the small residual strain exhibit the good superelastic properties in 10-time cyclic loading. The reduced elastic modulus (Er) of the Ti75Nb20Sn5 alloy (61 GPa) measured by using the nanoindentation technique is 2–6 times of that of human bone (10–30 GPa), and is smaller than that of commercial Ti-6Al-4V biomedical alloy (120 GPa). The Ti75Nb20Sn5 alloy can be considered as a novel biomedical alloy. The wear resistance (H/Er) and anti-wear capability (H3/Er2) values of the four alloys are higher than those of the CP–Ti alloy (0.0238), which indicates that the present alloys have good wear resistance and anti-wear capability.

The potential biomedical application near β-type Ti-35Nb-7Zr alloy with different CPP ceramic additions were evaluated in vitro using electrochemical method and osteoblasts co-cultured. A small amount addition of calcium pyrophosphate (CPP) ceramic induced the formation of oxide film on the surface of the composites that can withstand passive layer breakdown and the onset of localized forms of corrosion. But localized breakdown of the oxide layer occurred on composites as the CPP exceeded 20 wt%. Ti-35Nb-7Zr-10CPP exhibits a wide passive range in the polarization curve and gets a higher potential for inducing growth of bone-like apatite and proliferation of osteoblasts on its surface compared to that of the Ti-35Nb-7Zr, CP Ti and Ti6Al4V (TC4) alloys. The favorable cell viability and growth inside the pores of the composites arise from the rough micro-porous surface and the release of bioactive metal-ceramic phase ions into the physiological environment. Novel near β-type Ti-Nb-based alloys have attracted considerable attention for human bone implants due to their good mechanical properties, high corrosion resistance and low toxicity.1-3 Based on the Ti-Nb binary system, several near β-type Ti alloy containing nontoxic elements (Ta, Zr, Mo and Sn) have recently been developed for biomaterials. [4][5][6][7] Among them, Zr received renewed attention for surgical implants because it shows acceptable mechanical strength, satisfactory biocompatibility and corrosion resistance. In addition, Zr is a neutral element when dissolved in Ti and it can improve the strength. Zr-containing Ti alloys have been developed for commercial biomaterials. [8][9][10][11][12] It is reported that the elastic modulus of a near β-type Ti-Nb-Zr alloy at room temperature are about 40-55 GPa if the alloy composition and heat-treatment conditions are optimized. 10,13,14 This value is close to the elastic modulus of human bones (10-30 GPa) and it is conducive to reducing the stress shielding between natural bones and implants.15 Thus, β-type Ti-Nb-Zr alloys are considered to be one of the most promising alloys for biomedical applications. However, the osseointegration property of Ti-Nb-Zr alloys, which is necessary to promote bone tissue compatibility, is poorer than bio-ceramic materials because they are bio-inert. [15][16][17] Calcium pyrophosphate (Ca 2 P 2 O 7 , CPP) 18,19 is a bioactive ceramic material that has recently attracted wide attention in clinical orthopedic and bone repaired implants due to its similar chemical and crystallographic structure to natural bone apatite mineral. Maeda et al. 20 fabricated a CPP-Nb glass-ceramic, which mainly consisted of α-Ca 2 P 2 O 7 , β-Ca 2 P 2 O 7 and Nb 2 O 5 phases. In vitro tests revealed that CPP ceramic could significantly induce the formation and growth of bone-like apatite on the surface of the material. According to a research work from Lin et al., 21 a porous CPP-5 wt% Na 4 P 2 O 7 •10H 2 O ceramic was fabricated by powder sintering, and was implanted into New Zealand Rabbits. The vivo ...
