Abstract
A consumable-electrode, open-arc process was operated at pressures similar to those utilized in the electron-beam melting technique. Factors of arc instability, control of material processing rates, and chemical purity of the ingot product are discussed, with particular reference to the behavior of columbium, tantalum, and tungsten.
