ABSTRACT:
In this method for making an alloy of a first metal and a second metal which has a stronger tendency to form an oxide than the first metal, a powdered solid is prepared comprising at least one of a compound of the first metal with oxygen and the second metal, the compound is mixed with the second metal, and an alloying process is carried out of alloying a melt with the powdered solid, in which the second metal is oxidized by the oxygen of the compound of the first metal with oxygen which is reduced. The compound of the first metal with oxygen may be an oxide, and may be a simple oxide or a compound oxide. As one variation, the powdered solid may contain the compound of the first metal with oxygen, in which case the melt will contain the second metal; or alternatively the powdered solid may contain the second metal, in which case the melt will contain the compound of the first metal with oxygen. Alternatively, the powdered solid may contain both the compound of the first metal with oxygen and the second metal, in which case the melt may contain a third metal.
