A one-coil type Cold Crucible Levitation Melting furnace, with capacity of 100g and supplied by a frequency inverter power system, is used successfully for melting Ti-10Ta-20Nb, Ti-20Ta-30Nb and Ti-30Nb alloys under argon atmosphere of 7.4×104Pa, adopting supply conditions of 60kHz, 50kw/30sec for fusing the raw materials and 30kw/5min for homogenization. 70g ingots were gained, and then were analyzed by EPMA. The cast microstructure of all alloys presents dendrite-type. Elements almost distribute uniformly in ingots, only a Ta-rich bond is found in the lower part of some Ti-20Ta-30Nb and Ti-30Ta ingots. The real contents of Nb in all the samples are smaller than the nominal. Improving measures are also pointed out.
