摘要： A method of melt extraction of titanium alloys is provided. The alloys are those containing a high concentration of titanium and a significant amount of an alloying element selected from the group consisting of molybdenum, tantalum and columbium. Surprisingly, the extraction process is rendered feasible when the surface of the extracting mechanism is of molybdenum.
