Establishing a pathway for additively manufactured functionally graded structure from nickel-based superalloy to niobium-based refractory alloy

INVENTION REFERENCE NUMBER

202305308

  • Manufacturing
  • Materials

Using the current invention one may design composite parts with No based refractory alloys for hotter sections (needing more high temperature strength and creep resistance) while opting for relatively low cost and low gamma prime containing IN718 at zones operating below 1400F. It also circumvents welding issues while trying to join non-weldable Ni-base superalloys with Nb-based refractory alloys.
