Interdiffusion coefficientD D in the -phase of Ti-Al alloys has been determined by Matano's method in the temperature range 1323 to 1823 K with (pure Ti)-(Ti-8.5 at% Al alloy), (pure Ti)-(Ti-16.5 at% Al alloy) and (Ti-8.5 at% Al alloy)-(Ti-16.5 at% Al alloy) couples. In the whole temperature range the value ofD D increases gradually with increasing aluminum content. The Arrhenius plot ofD D up to 6 at% Al shows an upward curvature similar to that recognized in the self-diffusion in -Ti. The curvature becomes small with increasing aluminum content, and it is nearly linear in the concentration more than 10 at% Al. The activation energies for the impurity diffusion in -Ti are proportional to the square of radius of the diffusing atom. This suggests that the size effect is dominant in the impurity diffusion in -Ti.

“…The difficulty in locating the Matano interface in the BM method has been overcome by Den Broeder (DB) [9] by introducing a relative concentration variable. Although both BM and DB methods yielded identical results in Cu-Ni and Ta-W [10] systems, the latter is widely used due to its mathematical ease [11,12]. Based on our earlier investigations on heat-treated SS/TiTaNb explosive clads, an appreciable variation in molar volume with concentration is expected at temperatures beyond 700°C [4].…”

Dissimilar joints of 304L austenitic stainless steel (SS) and Ti-5Ta-2Nb alloy were fabricated using explosive cladding process with an aim to avoid the formation of brittle intermetallic phases at the interface. Subsequently, diffusion annealing heat treatments were carried out at temperatures in the range of 550-800°C for various durations. In the present study, concentration and temperature dependence of the distinct diffusion zones, formed at the clad interface, due to interdiffusion of the alloying elements, have been established using Electron Probe Micro Analysis and imaging of the interface. Molar volume showed a close match with the ideal Vegard's law at low temperatures while a non-linear negative deviation has been observed at high temperatures (800°C) due to the formation of secondary phases such as FeTi, Fe 2 Ti and bTi(Fe) phases. Interdiffusion parameters evaluated by Wagner's method showed sluggish diffusion kinetics of Fe and Ti at concentration corresponding to a two phase mixture of FeTi and Fe 2 Ti. Further, an attempt has been made to understand multicomponent diffusion using Dayananda's approach and estimation of effective interdiffusion coefficients revealed *22 lm shift of the interface from Matano plane at 800°C.

“…Thus, the precipitation of calcium phosphate must be inhibited. Zirconium and titanium belong to the same group (i.e., same column in the periodic table), have the same crystal structure, and have unlimited solubility in each other [ 35 ]. Furthermore, zirconium is expected to be an effective element for solution strengthening and, with respect to toxicity, is no more harmful than titanium [ 36 , 37 ].…”

The low Young's modulus of β-type titanium alloys makes them advantageous for use in medical implant devices, as they are effective in both preventing bone resorption and promoting good bone remodeling. The development of low Young's modulus β-type titanium alloys for biomedical applications is described herein, along with a discussion of suitable methods for even greater modulus reductions. Since there is often occasion to remove implant devices, titanium alloys suitable for removable implants are also described. It has recently been noted that although patients require low Young's modulus titanium alloys, a high modulus is needed by surgeons. Consequently, β-type titanium alloys with a self-tunable Young's modulus are also explored. An evaluation of the effectiveness of low Young's modulus β-type titanium alloys in preventing stress shielding is provided, which is based on the results of animal testing. Means of enhancing the mechanical biocompatibilities of β-type titanium alloys for biomedical applications are also described along with the suitability of those β-type titanium alloys which exhibit super-elastic and shape-memory behavior. Finally, the unique behavior of some β-type titanium alloys for biomedical applications is discussed.
