A cobalt-nickel-chromium-molybdenum alloy useful in surgical implant applications includes, in weight percent based on total alloy weight, at least 20 cobalt, 33.0 to 37.0 nickel, 19.0 to 21.0 chromium, 9.0 to 10.5 molybdenum, and less than 30 ppm nitrogen. Embodiments of the alloy lack significant levels of titanium nitride and mixed carbonitride inclusions. The alloy may be cold drawn to thin-gauge wire without damage to the die as may be caused by hard particle inclusions in certain conventional alloy formulations.

The present disclosure relates to electroslag remelting methods and apparatus for producing metallic ingots, as well as to articles of manufacture made from materials processed according to the methods and/or using the apparatus. One such method includes disposing slag within a withdrawal mold comprising a mold wall and an electrically conductive member disposed through the mold wall, contacting the slag with a consumable electrode, and heating the slag by conducting an electrical current through the consumable electrode into the slag, thereby melting at least a portion of the consumable electrode in contact with the slag. At least a fraction of the melted portion of the consumable electrode is collected in the withdrawal mold to form the ingot. At least a portion of the electrical current is conducted form the slag through the electrically conductive member.

A method of making an article includes forming a molten material by melting at least a portion of a mass of a metal and an alloy. The method further includes forming the article by solidifying at least a portion of the molten material within a mold, and contacting the article with plasma during formation of the article. A method for making an article also is disclosed wherein a molten material is formed by melting at least a portion of a mass of one of a metal and an alloy, the molten material is collected within a mold, and at least a portion of the molten material is magnetohydrodynamically stirred within the mold.

One non-limiting embodiment of an apparatus for forming an alloy powder or preform includes a melting assembly, an atomizing assembly, and a field generating assembly, and a collector. The melting assembly produces at least one of a stream of a molten alloy and a series of droplets of a molten alloy, and may be substantially free from ceramic in regions contacted by the molten alloy. The atomizing assembly generates electrons and impinges the electrons on molten alloy from the melting assembly, thereby producing molten alloy particles. The field generating assembly produces at least one of an electrostatic field and an electromagnetic field between the atomizing assembly and the collector. The molten alloy particles interact with the at least one field, which influences at least one of the acceleration, speed, and direction of the molten alloy particles. Related methods also are disclosed.
