Sound ingots of titanium and Ti–6Al–4V alloy,110-mm diam×400 mmlong, were cast in a 60-kW HHCD furnace. Oxygen and hydrogen levels were reduced considerably. Triple melting and casting of Nb–56Ti–3.3Zr alloy in an 80-kW HHCD furnace produced a satisfactory superconducting material on which test data is reported. A description of the furnace and the operating procedure is outlined.
