  • Heat treatment of NiCrFe alloy to optimize resistance to intergrannular stress corrosion
    Patent number: 4481043
    Abstract: A process of producing a NiCrFe alloy having a high resistance to stress corrosion cracking comprising heating a NiCrFe alloy to a temperature sufficient to enable the carbon present in the alloy body in the form of carbide deposits to enter into solution, rapidly cool the alloy body, and heat the cooled body to a temperature between 1100.degree. to 1500.degree. F. for about 1 to 30 hours.
    Type: Grant
    Filed: December 7, 1982
    Date of Patent: November 6, 1984
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Arthur F. Steeves, Albert E. Bibb
  • Micrographic detection of plastic deformation in nickel base alloys
    Patent number: 4445988
    Abstract: A method for detecting low levels of plastic deformation in metal articles comprising electrolytically etching a flow free surface of the metal article with nital at a current density of less than about 0.1 amp/cm.sup.2 and microscopically examining the etched surface to determine the presence of alternating striations. The presence of striations indicates plastic deformation in the article.
