| Abstract: | Objective： A new titanium alloy（Ti-12.5Zr-3Nb-2.5Sn） was developed to meet the needs of clinical requirements for medical titanium alloys and casting performance of Ti-12.5Zr-3Nb-2.5Sn alloy.Methods： Samples of a newly developed Ti-Zr-Nb-Sn alloy were prepared.Samples were casted by LZ5-centrifugal casting machine.Casting temperature of the titanium alloy and the casting flow rate were detected.Casting reaction layer and linear shrinkage were evaluated.Results： The casting flow rate was 100% when the alloy were casted at 400℃.Linear shrinkage and the surface reaction layer met the demands.Conclusions： Ti-12.5Zr-3Nb-2.5Sn alloy,as a dental restoration material,was proved to possess favorable mechanical and casting performance properties. |
