Electron Beam Melting and Refining of Metals and Alloys
Theincreasing need for improved refractory and reactive high strength materials has led to the development of special production processes. This article will consider electron beammelting and refining which is playing an important role especiaily in the production of nickel base superalloys, specialty steels, refractory metals such as tantalum, niobium, tungsten, and molybdenum and reactive metals such as hafnium, vanadium, zirconium, and titanium and their alloys.
