Disclosed is a wear-resistant Fe-Ni-Co-base alloy that is suitable for use as coatings, sintered powder metal parts, and material for application of hard-facing depositions and/or plating. The alloy preferably contains about 11% cobalt, 24% nickel, 3% each molybdenum and tungsten, 26% chromium, 1.3% silicon, 1% carbon, about 0.5% boron, up to 4% modifying elements Mn, V, Ta, Cb, Cu, La, Zr, R-E metals, and the balance essentially iron plus incidental impurities.

Wear-resistant iron-nickel-cobalt alloys

Disclosed is a process for recovering valuable metals from scrap including the steps of melting the initial scrap feed, carburizing the melt, solidifying the carburized melt, and recovering the valuable metals from the resultant material by an appropriate acid leaching step.

Process for recovering valuable metals from superalloy scrap

Disclosed is a method for recovering valuable metals from scrap including the steps of melting the initial scrap feed, carburizing the melt, solidifying the carburized melt, and recovering the valuable metals from the resulting material by ammoniacal leaching thereof.

A method is provided for producing ductile superalloys containing rare-earth metals, lanthanum and yttrium by melting the desired alloy composition by conventional melt practices, adding the rare-earth metals, lanthanum or yttrium to the molten composition, forming the alloy composition into solid electrodes, remelting the solid electrode by electroslag remelting techniques and casting the remelted alloy.
