Phase equilibrium, structure, mechanical and biocompatible properties of TiNi-based alloy with silver E. S. Marchenko, G. A. Baigonakova, O. V. Kokorev [et al.]

Contributor(s): Baigonakova, Gulsharat A | Kokorev, Oleg V | Klopotov, Anatoly A | Yuzhakov, Mikhail | Marchenko, Ekaterina SMaterial type: ArticleArticleSubject(s): фазовое равновесие | серебро | физико-механические свойства | интерметаллид никеля и титанаGenre/Form: статьи в журналах Online resources: Click here to access online In: Materials research express Vol. 6, № 6. P. 066559 (1-10)Abstract: The article presents a comprehensive study of the effect of different silver contents on the cells viability, structure and mechanical properties of TiNi-based alloy. Silver, crystallized in the form of pure particles, has a positive effect on cell viability. This is evidenced by a greater amount of cell mass on the surface of the alloy and an increase in the cell viability level by more than 30% at the presence of silver. A phase diagram of the Ag–Ni–Ti ternary system was constructed based on the structure of the two-component systems Ag–Ni, Ag–Ti and Ti–Ni and atoms from these systems. Due to the strong difference in the electronic structure and size factor of the components of the Ti–Ni–Ag ternary system, the limited solubility of Ag (~0.5 at% Ag) in the Ti–Ni binary compound was revealed. It has been established that the optimal combination of the physicomechanical properties of the alloys is achieved at silver concentrations, not exceeding 0.2 at% Ag.
