Abstract: A hybrid article is disclosed including a sintered coating disposed on and circumscribing the lateral surface of a core having a core material and a greater density than the sintered coating. The sintered coating includes more than about 95% up to about 99.5% of a first metallic particulate material including a first melting point, and from about 0.5% up to about 5% of a second metallic particulate material having a second melting point lower than the first melting point. A method for forming the hybrid article is disclosed including disposing the core in a die, introducing a slurry having the metallic particulate materials into a gap between the lateral surface and the die, and sintering the slurry. A method for welding a workpiece is disclosed including the hybrid article serving as a weld filler.

Abstract: An article and a method for forming the article are disclosed. The article comprising a composition, wherein the composition comprises, by weight percent, about 13.7% to about 14.3% chromium (Cr), about 9.0% to about 10.0% cobalt (Co), about 3.5% to about 3.9% aluminum (Al), about 3.4% to about 3.8% titanium (Ti), about 4.0% to about 4.4% tungsten (W), about 1.4% to about 1.7% molybdenum (Mo), about 1.55% to about 1.75% niobium (Nb), about 0.08% to about 0.12% carbon (C), about 0.005% to about 0.040% zirconium (Zr), about 0.010% to about 0.014% boron (B), and balance nickel (Ni) and incidental impurities. The composition is substantially free of tantalum (Ta) and includes a microstructure substantially devoid of Eta phase.
