Abstract: A mold for casting a titanium-containing article includes calcium aluminate and silicon carbide, and the silicon carbide is graded in the mold such that it is in different portions of the mold in different amounts, with the highest concentration of silicon carbide being located between a bulk of the mold and a surface of the mold that opens to a mold cavity.

Abstract: The disclosure relates generally to mold compositions and methods of molding and the articles so molded. More specifically, the disclosure relates to silicon carbide-containing mold compositions, silicon carbide-containing intrinsic facecoat compositions, and methods for casting titanium-containing articles, and the titanium-containing articles so molded.

Abstract: The disclosure relates generally to core compositions and methods of molding and the articles so molded. More specifically, the disclosure relates to core compositions and methods for casting hollow titanium-containing articles, and the hollow titanium-containing articles so molded.

Abstract: A mixing device having a mixing container and has a single-shaft agitator that extends into the mixing container. At the end of the drive shaft, a rotor body is arranged slightly above the bottom of the mixing container. The rotor body comprises a plurality of mixing blades, wherein the blades are, in one example, star-shaped and fixed in position to each other. A first end of the drive shaft is coupled to a motor and a second end of the drive shaft is configured to extend into the mixing vessel, wherein the blades are attached onto the second end of the drive shaft. The blades in one example include at least two coincidental knife-edged blades such that at least one of the knife-edged blades is facing upward. The mixing device in one example is used to mix calcium aluminate-containing slurries.

Abstract: The disclosure relates generally to mold compositions comprising calcium aluminate and calcium titanate. The disclosure also relates to methods of molding and the articles so molded using the mold compositions. More specifically, the disclosure relates to calcium aluminate/calcium titanate mold compositions and methods for casting titanium-containing articles, and the titanium-containing articles so molded.
