Definitions

  • Nickel-base superalloys are conventionally used as constructional materials for high-temperature service applications, such as the components for jet engines which are subject during service to high operating temperatures. In many applications the components made from these alloys must exhibit high strength and hardness at elevated temperatures. This is customarily achieved by increasing the alloy content of strengthening elements, such as titanium, aluminum, columbium, tantalum, hafnium, tungsten and molybdenum.
  • FIGS. 1, 2 and 3 are photomicrographs at a magnification of 100X of three compacted powder alloy articles, with the articles of FIGS. 1 and 2 being in accordance with the present invention and with the article of FIG. 3 being outside the scope of the present invention.
  • FIGS. 4, S and 6 are photographs at a magnification of 15X of the articles of FIGS. 1, 2 and 3, respectively, showing the features of specimens of these articles treated in tension.
  • nickel-base superalloys within the composition limits of Table I in the form of prealloyed powder and compacted to form articles having a density exceeding of theoretical, are characterized by a uniform distribution of minor phases. This, as will be shown hereinafter, provides articles of improved strength and ductility. Consequently, the term fully dense as used herein means a compacted article having a density exceeding 95% of theoretical density.
  • the size of the particles used for compacting in accordance with the present invention typically does not exceed minus 16 mesh US. Standard and generally will not exceed minus 30 mesh.
  • Alloys A and B of Table II are within the scope of this invention; whereas, Alloy C is outside the scope of the invention.
  • Prealloyed powder suitable for compacting was prepared from each of the alloys of Table II by melting a charge of the composition under an inert atmosphere, atomizing a stream of the molten metal by striking it with a jet of argon gas and subsequently rapidly cooling the atomized particles to ambient temperature.
  • the powder was collected and screened to minus 100 mesh and loaded in cylindrical mild-steel containers having a height of 9 inches and a diameter of 2.6 inches. The containers were evacuated to remove any moisture present therein and sealed against the atmosphere.
  • FIGS. 1, 2 and 3 are photomicrographs, as earlier described, of articles from Alloys A,, B and C, respectively.
  • FIGS. 4, 5 and 6 are photographs as earlier described of fractured tensile specimens of the articles of Alloys A, B and C, respectively.
  • the fracture of Alloy C, as shown in FIG. 6, is characterized by the ball and socket type fracture, which indicates fracture propagation along the spherical path of a particle boundary at which minor-phase concentration had occurred.
  • test specimen was machined from a consolidated powder product of Alloy A and tested in tension at 1950F under a constant head speed of 0.1 in./min.
  • the test temperature selected is representative of that normally used to fabricate nickel-base alloys into useful shapes by forging, extrusion or rolling. The results of the test were as follows:
  • a nickel-base superalloy compacted, fully dense article produced by elevated-temperature compacting of prealloyed powder particles consisting essentially of, in weight percent, carbon 0.15 to 0.25, chromium 10.5 to 14.5, cobalt 8 to 10, molybdenum l to 3, tungsten. 3 to 5, tantalum 3 to 5, titanium 3.2 to 5, aluminum 2.2 to 4.2, boron 0:00] to 0.03, zirconium 0.01 to 0.20, balance essentially nickel, said article being characterized by the absence of minor phase concentrations at prior powder-particle boundaries.
  • a nickel-base superalloy compacted, fully dense article produced by elevated-temperature compacting of prealloyed powder particles consisting essentially of, in weight percent, carbon 0.01 to 0.20, chromium 12 to 16, cobalt 7 to 9, molybdenum 2.5 to 4.5, tungsten 2.5 to 4.5, columbium 2.5 to 4.5, titanium 1.5 to 3.5, aluminum 2.5 to 4.5, boron 0.001 to 0.03, zirconium 0.01 to 0.20, balance essentially nickel, said article being characterized by the absence of minor phase concentrations at prior powder-particle boundaries.
  • prealloyed powder particles consisting essentially of, in weight percent, carbon 0.2 to 0.4, chromium 10 to 14, cobalt 9 to 11, molybdenum l to 4, tungsten 5 to 7, tantalum 0.5 to 2.5, titanium 2 to 4, aluminum 3.5 to'5.5, boron 0.001 to 0.03, zirconium 0.01 to 0.20, balance essentially nickel, said article being characterized by the absence of minor phase concentrations at prior powder-particle boundaries.
