摘要： A method of investment casting includes casting a liquid nickel- or cobalt-based superalloy in an investment casting mold. The superalloy includes an yttrium alloying element that is subject to reactive loss during the casting. Loss of the yttrium is limited by using a zircon-containing facecoat on a refractory investment wall in the investment casting mold. The facecoat contacts the liquid nickel- or cobalt-based superalloy during the casting. Prior to the casting, a zircon-containing slurry is used to form the facecoat. After solidification of the nickel- or cobalt-based superalloy, the refractory investment wall is removed from the solidified superalloy.

摘要： A method of purifying and casting a material comprising placing a material to be purified within a crucible, the crucible located within a purification chamber; providing thermal energy to the material to maintain the material in a molten state; providing a purification gas into the molten material to purify the material until a first measured condition is attained; passing the material in a fluid state from the purification chamber having a first atmosphere to a casting chamber having a second atmosphere, the purification chamber in fluid communication with the casting chamber such that the material passes from the purification chamber to the casting chamber without exposure to a third atmosphere; placing the material into a mold within the casting chamber; cooling the material within the mold to form a cast material.

摘要： An apparatus and method for enhanced gravity casting wherein a portion of the mold is maintained in pressure contact with molten metal as it solidifies to allow the mold surface to follow the contraction of the solidifying metal. A further feature of the invention is the use of an air clearance between mold parts that is sufficient to allow air to escape but insufficient to allow molten metal to flow therepast.
