Abstract: An article is made by preparing an elongated preform having a net metallic composition, and including a tubular sheath made of a sheath nickel-base alloy, and a core disposed within the tubular sheath and including consolidated powder particles made of a core nickel-base alloy. The net metallic composition is preferably a nickel-base superalloy, and most preferably a high-gamma-prime nickel-base superalloy. The preform is wire drawn to a final maximum transverse size that is less than the initial maximum transverse size, to produce a drawn article. The drawn article may be used as a weld filler material.
