Abstract:

Vacuum arc melting of experimental refractory metals at the Experimental Metals Processing Facility is summarized. The influence of fur nace design modifications and melt variables on electrode melt rates is shown. Minor additions of oxygen and titanium to tungsten electrodes reduce the melt rate and additions of carbon and zirconium cause no significant change in melt rate. Increased melting current also increases electrode consumption rate. In general, coarser macrostructures are associated with slower melt rates. Author
