Investigation into the Production of Metastable Nb sub 3 Ge Powder Via the Rotating Electrode Process

摘要

The production of metastable Nb sub 3 Ge powder via the rotating electrode process (REP) employing ''splat cooling'' was investigated. An electrode capable of withstanding the thermal shock of the electric arc used in REP was produced through powder metallurgy techniques. The effect of various parameters involved in the rotating electrode process was studied in correlation with process control and crystal structure, microstructure and compositional analyses of the powder produced. Superconducting transition temperature measurements were made on the powder both as-produced and after annealing experiments. (ERA citation 03:057160)
