| Abstract: | Objective： To study the mechanical properties of a new titanium alloy with Ti-12.5Zr-3Nb-2.5Sn. Methods： Samples of a newly developed Ti-Zr-Nb-Sn alloy were prepared. The mechanical properties were measured by tensile test. The microstructure and microhardness profile of the specimen section were measured by metallurgical microscope and mi- crohardness test meter. Results： The data of the tensile strength （MPa）, yield strength （MPa）, elongation（%）, elastic modulus （GPa） and microhardness （HV） of the Ti-Zr-Nb-Sn alloy were 671.3, 561.5, 18.1, 92.5 and 250.7 respectively. The microstructure showed fine crystal grains. Conclusion： The microstructure and the mechanical properties of the Ti-Zr-Nb-Sn alloy may meet the requirement for dental restoration |
