Mechanical properties and microstructures of new Ti–Fe–Ta and Ti–Fe–Ta–Zr system alloys

Wear response of heat-treated Ti–13Zr–13Nb alloy in dry condition and simulated body fluid

“…The solution treatment temperature had a relatively small effect on the hardness of air-cooled and water-quenched samples. It has been reported [24,25] that the precipitation of ␣ phase in the matrix increases the hardness of the ␤ titanium alloys. In the present study, the higher volume fraction of ␣ phase and its fine distribution in the matrix increased the hardness.…”

Production, Microstructural Characterization and Mechanical Properties of As‐Cast Ti‐10Mo‐xNb Alloys

“…β‐type Ti alloys consisting of nontoxic elements have been developed to achieve lower Young's modulus and higher strength. Tantalum (Ta), zirconium (Zr), niobium (Nb), and molybdenum (Mo) are suitable elements to increase the strength and decrease the Young's modulus of β‐type Ti alloys (1,2, 6–8). Among the β‐type Ti alloys, body‐centered cubic (BCC) metastable β‐Ti possesses the lowest elastic modulus and satisfies several other requirements for an ideal alloy (9–12).…”

The influence of heat treatment and role of boron on sliding wear behaviour of ββ-type Ti–35Nb–7.2Zr–5.7Ta alloy in dry condition and in simulated body fluids

“…Promises of properties better than those of the existing titanium alloys (Ti-6Al-4V, Ti-6Al-7Nb, Ti-5Al-2.5Fe etc.) for implants and scope of wide use particularly for load bearing applications have drawn the attention of many researchers in recent years Banerjee et al, 2005;Kuroda et al, 1998Kuroda et al, , 2005Li et al, 2004a;Niinomi, 2003;Niinomi et al, 2005;Sagaguchi et al, 2005a;Takahashi et al, 2000;Zorn et al, 2005). However, poor tribological properties of titanium and its alloys reduce the service life of the implants significantly.…”
