THE EVOLUTION OF NICKEL-BASE PRECIPITATION-HARDENING SUPER-ALLOYS
Technical Report
·
OSTI ID:4078119
Each of the superalloys falls within one of three groups: nickel-base, cobalt-base, or iron-nickel-chromium-base. The nickel-base alloys are basically nickel-chromium alloys, which derive their high-temperature strength from both precipitation and solid solution hardening. Precipitation hardening is accomplished by the addition of aluminum and titanium, whereas solid-solution hardening is accomplished by the addition of one or more of the elements molybdenum, tungsten, or niobium.
