  • Publication number: 20190314896
    Abstract: Process for producing a titanium alloy material, such as a titanium aluminum alloy, are provided. The process includes reduction of TiCl4), which includes a titanium ion (Ti4+), through intermediate ionic states (e.g., Ti3+) to Ti2+, which may then undergo a disproportionation reaction to form the titanium aluminum alloy.

  • Publication number: 20190270140
    Abstract: Processes are provided for producing a titanium alloy material, such as Ti—Al alloys. In one embodiment, the process includes: heating an input mixture to a preheat temperature with the input mixture including aluminum, optionally, AlCl3, and, optionally ally, one or more alloying element halide; introducing TiCl4 to the input mixture at the first reaction temperature such that substantially all of the Ti4+ in the TiCl4 is reduced to Ti3+; thereafter, heating to a second reaction temperature such that substantially all of the Ti3+ is reduced to Ti2+ to form an intermediate mixture (e.g., a Ti2+ salt); and introducing the intermediate mixture into a reaction chamber at a disproportionation temperature reaction to form the titanium alloy material from the Ti2+ via a disproportionation reaction.

  • Patent number: 9539640
    Abstract: A casting system, apparatus, and method. The casting system can include an energy source and a hearth, which can have a tapered cavity. The tapered cavity can have a first end portion and a second end portion, and the tapered cavity can narrow between the first and second end portions. Further, the tapered cavity can have an inlet at the first end portion that defines an inlet capacity, and one or more outlets at the second end portion that define an outlet capacity. Where the cavity has a single outlet, the outlet capacity can be less than the inlet capacity. Where the cavity has multiple outlets, the combined outlet capacity can match the inlet capacity. Further, the cross-sectional area of the tapered cavity near the inlet can be similar to the cross-sectional area of the inlet.
