Claims12
A method of melting an alloy in an induction furnace, comprising charging an induction furnace with metallic raw materials of generally elemental metallics, at least a portion of which contain greater than 100 ppm of oxygen in any form, charging said induction furnace with boron in any form in an amount of at least 0.02% by weight of the total charge, melting said charge materials in said induction furnace and thereafter pouring the melt from the furnace into a mold for solidification and formation of an ingot.
