Description
Summary:Here we report on the structure and mechanical properties of low-alloyed Ti-based alloys containing Ag subjected to a dual-axial forging operation. The dependence of the microstructure and mechanical properties on the regimes of the dual-axial forging operation is studied for the Ti94Ag3Pd3 alloy having the optimal properties. The hemolytical activity of the Ti94Ag3Pd3 alloy was also investigated. The percent hemolysis induced by the sample after 5 h of incubation is much lower than that for the surgical titanium after 4 h of incubation. Doping of the Ti94Ag3Pd3 by a minor amount of nitrogen (N) improved its mechanical properties and decreased its elastic modulus (to 65 MPa), which is attractive for biological applications. •Ti94Ag3Pd3 alloy showed the most attractive mechanical properties.•Hemolysis induced by Ti94Ag3Pd3 is much lower than that induced by titanium.•Nitrogen improved mechanical properties of the Ti94Ag3Pd3 alloy.•Tensile strength is more than 1000 MPa, the elongation is about 15%.•The elastic modulus is 65 MPa.
