Abstract: A process for directional solidification of a cast part comprises energizing a primary inductive coil coupled to a chamber having a mold containing a material; energizing a primary inductive coil within the chamber to heat the mold via radiation from a susceptor, wherein the resultant electromagnetic field partially leaks through the susceptor coupled to the chamber between the primary inductive coil and the mold; determining a magnetic flux profile of the electromagnetic field; sensing a magnetic flux leakage past the susceptor within the chamber; generating a control field from a secondary compensation coil coupled to the chamber, wherein the control field controls the magnetic flux experienced by the cast part; and casting the material within the mold under the controlled degree of flux leakage.

Abstract: A method of manufacturing a heat shield panel assembly is provided. The method comprising: forming a heat shield panel, wherein the heat shield panel comprises one or more orifices; and forming each of one or more threaded studs through operations comprising: injecting melted wax into a negative cavity of a threaded stud; allowing the wax to solidify to form a positive pattern of the threaded stud; removing the positive pattern of the threaded stud from the negative cavity of the threaded stud; coating the positive pattern of the threaded stud with a ceramic; melting the positive pattern of the threaded stud away from the ceramic, the ceramic having a second cavity forming a second negative cavity of the threaded stud; pouring melted metal into the second cavity; allowing metal in the second cavity to solidify to form the threaded stud; and removing the ceramic from the threaded stud.

Abstract: A method of fabricating an investment casting mold includes using a zircon-containing slurry to form a facecoat of a refractory investment wall of a mold cavity in an investment casting mold. The zircon-containing slurry includes, by weight, at least 70% of zircon powder. Also disclosed is a slurry for use in an investment casting mold. The slurry includes, by weight, at least 70% of zircon powder, 10%-30% of colloidal silica material, and 1%-10% of a carrier solvent. The method and slurry can be used to fabricate an investment casting mold that has a refractory investment wall with a facecoat having, by weight, at least 70% zircon.

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.
