  • High temperature alloys
    Patent number: RE29920
    Abstract: Nickel base superalloys in which critical amounts of boron are employed to enhance creep-rupture strength and ductility in the 1,300.degree. F.-1,800.degree. F. temperature range. Creep-rupture strength and ductility at temperatures around 1,800.degree. F. also is enhanced by employing amounts of carbon below a critical upper limit. These alloys are particularly useful in the form of castings as gas turbine engine components.
