“…It is also suggested that the thermodynamic model agrees well with the experimental phase diagram [10]. There are nine phases: liquid, β-Ti (bcc), α-Ti (hcp), β-Sn (bct), α-Sn, Ti 3 Sn, Ti 2 Sn, Ti 5 Sn 3 and Ti 6 Sn 5 . The composition range of solution phase β-Ti and α-Ti in Ti-Sn system is 0-7.5 at.…”

Isothermal section of Ti-Nb-Sn at 1173 K was experimentally studied by back-scattered electron, electron probe microanalysis and X-ray diffraction analysis. Solid solution phase β(Ti, Nb), liquid Sn and eight intermetallic compounds Ti 3 Sn, Ti 2 Sn, Ti 5 Sn 3 , Ti 6 Sn 5 , Nb 6 Sn 5 , Nb 3 Sn, Ti 3 Nb 2 Sn 2 and Ti 3 NbSn coexisted. Four ternary phase regions Ti 3 Sn + Ti 3 NbSn + β(Ti, Nb), Ti 3 NbSn + Ti 3 Nb 3 Sn 2 + Ti 3 Sn, Ti 2 Sn + Ti 3 Sn + Ti 3 Nb 3 Sn 2 and Ti 6 Sn 5 + Ti 3 Nb 3 Sn 2 + Nb 3 Sn were experimented. In addition, the proper composition range of the single phase was suggested. All the detected Ti-Sn and Nb-Sn compounds have a remarkable solubility along the isoconcentration of Sn. β(Ti, Nb) has a relatively large solution while liquid Sn has a little in the isothermal section.

“…They are promising materials in many fields especially in a biomedical aspect. Nb and Sn are alloy elements of biocompatibility, and do not increase the martensitic transformation temperature of metastable β titanium alloys [1][2][3][4][5][6]. It is necessary to know the phase equilibrium in Ti-Nb-Sn ternary system.…”

“…Zr and Sn are very effective in suppressing the α ′′ martensitic transformation of alloys based on Ti-Nb, and the addition of 1 wt% of Zr and Sn reduces the martensitic start temperature by 41.2 K and 40.9 K, respectively, as compared to 17.6 K by 1 wt% of Nb (Hao et al, 2006). First principles computations (Hu et al, 2008) suggest that the addition of Nb to Ti increases both the elastic and phase stability of the β.…”

“…ϕ is angles between longitudinal and rolling directions in specimen, and M s is α 00 martensitic transformation temperature [11] temperatures just below these temperatures [16]. Newly developed β-type Ti alloys such as Ti-Nb-Ta-Zr [7,8], Ti-Nb-Sn [16,9,15], Ti-Nb-Al [11,17], Ti-Nb-Ta [18], and Ti-Nb-Zr-Sn [10] alloys are considered to satisfy the abovementioned requirements for obtaining low Young's modulus of the order of 40-60 GPa, which is close to that of the bone (10-30 GPa) [19]. However, the mechanical reliability of these β-type Ti alloys with low Young's modulus is typically lesser than that of a common (α + β)-type Ti-6Al-4V ELI alloy.…”

This chapter aims to review the recent trends pertaining to the enhanced functionalities, including low Young's modulus, self-tunable Young's modulus, and low magnetic susceptibility, of titanium and zirconium alloys for use in orthopedic implants. These value-added functionalities can be realized by controlling the type of crystal structure and their lattice structure stabilities, which are related to the phase stability of titanium and zirconium alloys. Keywords Magnetic susceptibility • Metallic materials • Orthopedic implant • Phase stability • Young's modulus IntroductionOne of the most important factors concerning the use of orthopedic implants is to ensure safety in usage, which is often associated with their mechanical reliability to endure physiologically cyclic loading and unexpected large loads during treatment. Given these considerations, metallic materials are advantageous over ceramic and polymeric materials for use as implantable materials. Therefore, more than 80 % of the implant devices used till date are made of metallic materials [1]. Another important factor concerning the use of orthopedic implants is their toxicity toward living tissues. In general, the human body inherently resists any incoming toxic element. In other words, human body exhibits low permittivity to highly toxic elements eluted from orthopedic implants [2]. That is, the toxicity of orthopedic implants depends not only on the nature of the metallic elements but also on the amount of them, which, in turn, strongly depends on the corrosion resistance of each metallic material. Therefore, in the human body, a metallic material with high corrosion resistance is highly imperative to ensure their safe usage as orthopedic implants.
