摘要： A method of melting and refining an alloy comprises vacuum induction melting starting materials to provide a vacuum induction melted alloy. At least a portion of the vacuum induction melted alloy is electroslag remelted to provide an electroslag remelted alloy. At least a portion of the vacuum arc remelted alloy is vacuum arc remelted to provide a singly vacuum arc remelted alloy. At least a portion of the singly vacuum arc remelted alloy is vacuum arc remelted to provide a doubly vacuum arc remelted alloy. In various embodiments, a composition of the vacuum induction melted alloy comprises primarily one of vanadium, chromium, manganese, iron, cobalt, nickel, copper, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, tantalum, tungsten, rhenium, osmium, iridium, platinum, and gold.
