ABSTRACT There is disclosed a process for desulfurizing transition metal alloys, particularly in a vacuum induction melting process where the absence of slag is desirable. The process is effected by adding any dilute calcium bearing binary alloy such as an ally of calcium and nickel or an alloy of calcium and aluminum t o the transition metal alloy while it is in the molten state and in contract with an atmosphere that is substantially free of oxygen.
