Abstract: Forging processes are described for cast superalloys. The forgeability of superalloy materials is improved by the development of overaged microstructure. The total forging process is usually performed in a series of steps with intervening heat treatments to reform the overaged microstructure.

Abstract: Heat treatments are described which improve subsequent HIP treatment results of superalloy articles. The heat treatments substantially eliminate certain low melting phases which otherwise would cause problems relating to gas entrapment during a HIP process. The articles are heated to a temperature near but below the intended HIP temperature for a period of time sufficient to reduce the low melting phase.

Abstract: Pre-Hip Heat Treatment of Superalloy Castings Heat treatments are described which improve subsequent HIP treatment results of superalloy articles. The heat treatments substantially eliminate certain low melting phases which otherwise would cause problems relating to gas entrapment during a HIP process. The articles are heated to a temperature near but below the intended HIP temperature for a period of time sufficient to reduce the low melting phase.

Abstract: Provided is a cast nickel-base superalloy having improved machinability characteristics having a formulation by weight percent of: upto 0.017 carbon, 0 - 0.015 phosphorus, 0 - 0.015 sulfur 17.00 - 21.00 chromium, 50.00 - 55.00 nickel, 2.80 - 3.30 molybdenum, 4.40 - 5.50 niobium and tantalum combined, 0.30 - 0.80 aluminum, 0.65 - 1.15 titanium, 0 - 0.006 boron, 0 - 0.35 manganese, 0 - 1.00 cobalt, 0 - 0.35 silicon, 0 - 0.30 copper, and the balance iron. The cast article may be hot-isostatically pressed at a temperature and pressure sufficient to substantially reduce segregation within the nickel-base superalloy, and thereafter heat-treated to achieve a fill precipitation heat-treated condition, which substantially increases the strength of the superalloy. Subsequent to hot-isostatic pressing and heat-treatment, the cast article has a standard machinability rating of at least 13% when compared to an AMS5010 steel.
