The electron-beam melting process offers the potential of purifying high-melting-point materials because of the high temperatures and vacuums attainable. The results of studies of the effects of electron-beam melting on metals and compounds are presented. The metals evaluated were: beryllium, boron and boron alloys, cobalt, hafnium, tungsten, and vanadium. The compounds included: titanium carbide, tantalum carbide, and zirconium di-boride. In addition, deoxidation studies were carried out on beryllium, molybdenum, and vanadium and the results obtained are presented.
