Abstract: A method for heat treating a superalloy component includes heating a superalloy component to a first temperature, cooling the superalloy from the first temperature to a second temperature at a first cooling rate in a furnace, and cooling the superalloy component from the second temperature to a final temperature at a second cooling rate. The second cooling rate is higher than the first cooling rate.

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.
