Abstract: Methods and apparatus for producing large diameter superalloy ingots are disclosed. A material comprising at least one of a metal and a metallic alloy is introduced into a pressure-regulated chamber in a melting assembly. The material is subjected to a wide-area electron field within the pressure-regulated chamber to heat the material to a temperature above the melting temperature of the material to form a molten alloy. At least one stream of molten alloy from the pressure-regulated chamber is provided from the melting assembly and is fed into an atomizing assembly, where particles of the molten alloy are generated by impinging electrons on the molten alloy to atomize the molten alloy. At least one of an electrostatic field and an electromagnetic field are produced to influence the particles of the molten alloy. The particles of the molten alloy are deposited onto a collector in a spray forming operation to form an alloy ingot.
