Abstract

Precipitation hardening, austenitic type superalloys are described. These alloys contain 0.5 to 1.5 weight percent silicon in combination with about 0.05 to 0.5 weight percent of a post irradiation ductility enhancing agent selected from the group of hafnium, yttrium, lanthanum and scandium, alone or in combination with each other. In addition, when hafnium or yttrium are selected, reductions in irradiation induced swelling have been noted.

High post-irradiation ductility thermomechanical treatment for precipitation strengthened austenitic alloys

Patent Laidler, James J [Richland, WA]; Borisch, Ronald R [Kennewick, WA]; Korenko, Michael K [Rockville, MD]

A method for improving the post-irradiation ductility is described which prises a solution heat treatment following which the materials are cold worked. They are included to demonstrate the beneficial effect of this treatment on the swelling resistance and the ductility of these austenitic precipitation hardenable alloys.

Method and apparatus for welding precipitation hardenable materials

Patent Murray, Jr., Holt (Hopewell, NJ); Harris, Ian D [Dublin, OH]; Ratka, John O [Cleveland Heights, OH]; ...

A method for welding together members consisting of precipitation age hardened materials includes the steps of selecting a weld filler material that has substantially the same composition as the materials being joined, and an age hardening characteristic temperature age threshold below that of the aging kinetic temperature range of the materials being joined, whereby after welding the members together, the resulting weld and heat affected zone (HAZ) are heat treated at a temperature below that of the kinetic temperature range of the materials joined, for obtaining substantially the same mechanical characteristics for the weld and HAZ, as for the parentmore » material of the members joined.« less

Precipitation hardenable iron-nickel-chromium alloy having good swelling resistance and low neutron absorbence

Patent Korenko, Michael K [Richland, WA]; Merrick, Howard F [Suffern, NY]; Gibson, Robert C [Ringwood, NJ]

An iron-nickel-chromium age-hardenable alloy suitable for use in fast breeder reactor ducts and cladding which utilizes the gamma-double prime strengthening phase and characterized in having a morphology of the gamma-double prime phase enveloping the gamma-prime phase and delta phase distributed at or near the grain boundaries. The alloy consists essentially of about 40-50% nickel, 7.5-14% chromium, 1.5-4% niobium, 0.25-0.75% silicon, 1-3% titanium, 0.1-0.5% aluminum, 0.02-0.1% carbon, 0.002-0.015% boron, and the balance iron. Up to 2% manganese and up to 0.01% magnesium may be added to inhibit trace element effects; up to 0.1% zirconium may be added to increase radiation swellingmore »« less

Barrier layer for a MCrAlY basecoat superalloy combination

Patent Sabol, Stephen M [Orlando, FL]; Goedjen, John G [Oviedo, FL]; Vance, Steven J [Orlando, FL]

A turbine component contains a substrate (22) such as a superalloy, a basecoat (24) of the type MCrAlY, and a continuous barrier layer (28) between the substrate and basecoat, where the barrier layer (28) is made of an alloy of (Re, Ta, Ru, Os)X, where X can be Ni, Co or their mixture, where the barrier layer is at least 2 micrometers thick and substantially prevents materials from both the basecoat and substrate from migrating through it.
