  • Turbine blade superalloy II
    Patent number: 5006163
    Abstract: A novel, nickel-base, high temperature alloy body preferably containing about 20% chromium, 6 to 7% aluminum to provide phase, 1.5 to 2.5% molybdenum, 3 to 4.5% tungsten, additional strengthening elements and oxidic yttrium in finely dispersed form. The alloy body has an elongated crystal structure and is characterized by high strength along with excellent hot corrosion and oxidation resistance.
    Type: Grant
    Filed: May 8, 1989
    Date of Patent: April 9, 1991
    Assignee: Inco Alloys International, Inc.
    Inventors: Raymond C. Benn, Jeffrey M. Davidson, Kenneth R. Andryszak
