| Gaia: | Title screen In the present work, we report the preparation of a novel titanium-based alloy, namelyTi25Nb10Zr, by cold crucible levitation melting technique. The cast alloy consists of acomplex microstructure with large Beta phase grains (54%, 50-150 [mu]m) with a regularly con-nected net of Alpha (orthorhombic, 46%) phase running along boundaries and across thegrains and keeping a regular misorientation with respect to the Beta phase. An intermeshed 51% Alpha and 49% Beta phases with lamellar microstructure were found by annealing. Theelectrochemical tests showed that both alloys were affected by the corrosion process. Agood corrosion resistance in SBF at 37°С was found for the cast form. The cast alloy is moreresistant when immersed into solutions with pH2 and pH7, while the annealed one is resis-tant in pH5 solution. Surface potential of both alloys is negative, with the annealing processleading to a slight decrease of that property. Collectively, the biological results indicate amore favorable viability on cast form as compared to annealed one, suggesting that the castalloy is promising for biomedical applications. |
