摘要

Superconductivities and structural properties of Ti - Zr - Ta ternary alloys are extensively investigated. The TiZrTa sample has a cubic structure (β-phase) and shows a sharp superconducting transition at a critical temperature (T_c) of about 7.3 K. In addition, two series of Ti - Zr - Ta alloys, with nominal compositions of Ti_65-xZr₃₅Ta _x and Ti_xZr_65-xTa₃₅ respectively, are prepared, and their superconductivities and crystal structures change regularly with the chemical composition. Our experimental study also indicates that the annealing processing of this kind of material can cause the transition temperature to increase and the highest T_c is observed to be about 8.3 K in annealed samples.
