Abstract: A die casting system includes a die including a plurality of die components that define a die cavity, a single crystal shot tube in fluid communication with the die cavity, and a shot tube plunger tip moveable within the shot tube to communicate a charge of a molten or semi-molten material into the die cavity. The system further includes a vacuum chamber that applies a vacuum to render a die casting process wherein at least a portion of the die is positioned within the vacuum chamber.

Abstract: A method for casting an article comprises a first region and a second region. The method comprises casting an alloy in a shell, the shell having a casting core protruding from a first metal piece; and deshelling and decoring to remove the shell and core and leave the first region formed by the first piece and the second region formed by the casted alloy.

Abstract: High modulus turbine shafts and high modulus cylindrical articles are described as are the process parameters for producing these shafts and cylindrical articles. The shafts/articles have a high Young's modulus as a result of having high modulus crystal texture along the longitudinal axis of the shaft/article. The shafts are produced from directionally solidified seeded single crystal cylinders that are axisymmetrically hot worked before a limited recrystallization process is carried out at a temperature below the recrystallization temperature of the alloy. The disclosed process produces an intense singular texture and results in shaft or cylindrical article with a Young's modulus that is at least 40% greater than that of conventional nickel or iron alloys or conventional steels.
