  • Patent number: 9011205
    Abstract: Titanium-containing articles having improved surface finishes and methods for changing the surface of titanium containing articles, for example by removing overstock, are provided. One example method includes passing a fluid at high pressure across a surface of an titanium aluminide alloy-containing article, for example, a turbine blade, at high linear speed and deforming the surface of the titanium aluminide alloy-containing article, and removing material from the surface of the titanium aluminide alloy-containing article. Though aspects of the invention can be used in fabricating high performance turbine blades, the methods disclosed can be applied to the treatment of any titanium-containing article for which it is difficult to obtain an improved surface finish.

  • Publication number: 20150033982
    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.

  • Publication number: 20140076512
    Abstract: The present disclosure relates to a titanium-containing article casting mold composition comprising calcium aluminate and an X-ray or Neutron-ray detectable element. Furthermore, present embodiments teach a method for detecting sub-surface ceramic inclusions in a titanium or titanium alloy casting by combining calcium aluminate, an element more radiographically dense than the calcium aluminate, and a liquid to form a slurry; forming a mold having the calcium aluminate and the radiographically dense element from the slurry; introducing a titanium aluminide-containing metal to the radiographically dense element-bearing mold; solidifying said titanium aluminide-containing metal to form an article in the mold; removing the solidified titanium aluminide-containing metal article from said mold; subjecting the solidified titanium aluminide-containing article to radiographic inspection to provide a radiograph; and examining said radiograph for the presence of the radiographically dense element on or in the article.

  • Patent number: 8590595
    Abstract: One embodiment is a method. The method includes providing a casting apparatus including a first chamber and a second chamber, wherein the first chamber is isolated from the second chamber. The method includes charging an alloy composition into a crucible present in the first chamber and melting the alloy composition in the crucible to form a molten alloy composition. The method includes discharging the molten alloy composition into a casting mold present in the second chamber; applying a positive pressure to the first chamber to create a first chamber pressure; and applying a vacuum to the second chamber to create a second chamber pressure, wherein the first chamber pressure is greater than the second chamber pressure. The method further includes casting a filament or a turbine component from the molten alloy composition in the casting mold. An apparatus for casting a filament or a turbine component is also provided.
