“…In addition, it can be seen that the lamellar Zr 3 Cu in the eutectoid structure shows a trend of increasingly irregular growth with the increase in doping elements in the high-magnification image. The other results [12,15] found that Nb has an obstructive effect on the diffusion of Cu in zirconium alloys. The greater the content of Nb, the more significant the obstructive effect of Nb on Cu.…”

“…Actually, when the Cu content is 4 at.% in the zirconium alloy, the formation of Zr 2 Cu is affected by the cooling conditions. The Zr alloys are designed by considering the second-phase strengthening mechanism through addition of the 4 at.% Cu element to form the phase Zr 3 Cu [12] and the solid solution strengthening by adding the Nb and Sn elements. Improvement of the friction and wear properties may be expected for the addition of Nb and Sn with good lubricating characteristics [13].…”

The problems of high elastic modulus and poor friction and wear properties should be investigated and solved for further promotion of the application of biomedical alloys. For the first time, Zr-4Cu-xNb-xSn (x = 0, 0.25, 0.5, 1) biomedical alloys with low elastic modulus and excellent tribological performance are designed and vacuum smelted in this work. Phase analysis and microstructural observation indicate that the Zr-4Cu-xNb-xSn alloys consist of two phases, i.e., α-Zr and Zr 3 Cu. Zr 3 Cu is mainly concentrated in the grain boundary and the eutectoid structure. With the increase in Nb and Sn contents, content of the grain boundary Zr 3 Cu changes in a zigzag manner. Compression tests indicate that the alloys have low elastic modulus (25.2-27.45 GPa), high compressive strength (1024-1139 MPa) and elastic energy (7.14 MJ/m 3-11.80 kJ/m 3). Compressive fracture behaviors have been investigated concerning the mechanism with alloying contents and microstructure. Through the tribological test in artificial saliva, it is indicated that the Zr-4Cu-xNb-xSn alloys have better friction and wear properties than pure titanium. Wear mechanism of the alloys is mainly abrasive wear and fatigue wear.

The progress of metallic structural biomaterials, mainly titanium alloys, for implants with mainly focusing on mechanical biocompatibility is described. Mechanical biocompatibility includes not only Young s modulus but also broad sense of mechanical biocompatibilities such as balance of strength and elongation, fatigue endurance (fatigue strength) and fracture toughness. Specially, the present paper focuses on developments of high fatigue strength of (α + β)-type titanium alloys composed of non-toxic elements, low Young s modulus β-type titanium alloys composed of non-toxic and allergy-free elements, Young s modulus self-adjustable β-type titanium alloys composed of non-toxic elements, Ni-free β-type titanium alloys for biomedical applications. Ni-free stainless steels and Co-Cr-Mo alloys, cell viability of pure metals, and some very recent research and development topics are also brie y introduced in the present paper.
