| Abstract | Induction melting of titanium alloys using a semi-levitation technique and bottom pouring in graphite crucible was evaluated for four titanium alloys, Ti--6Al--4V, Ti--6Al--2Sn--4Zr--2Mo, Ti--3Al--8V--6Cr--4Mo--4Zr (Beta C), and Ti--11Mo--4.5Sn--6Zr (Beta 111). Precision investment (lost wax) casting molds coated with pyrolytic graphite were used with the melting technique to make castability, tensile specimen, and bearing housing segment castings. Castability and tensile properties of the alloys were characterized. Bearing housing segments were subject to porosity which was extensively studied. Process capabilities and limitations were investigated for induction melting and the pyrolytic graphite coated mold. Properties of castings were determined, and weldability of the four cast alloys was evaluated. Effects of the casting process on microstructure were investigated. (auth) |
