ABSTRACTThe effect of thermal processing in the sample preparation of YBa2Cu3Oy has been investigated systematically on microstructures and electrical properties. The grain size was found to grow preferably during the cooling process rather than during the sintering process. The high Tc superconducting phase appears around 500 C in this thermal processing. The annealing experiment shows that the grains still grow at low temperature such as 300 °C.

ABSTRACTThe application of low temperature ion bombardment and pulsed laser or electron beam irradiation for the production of rapidly quenched superconducting alloys is described and compared with other more conventionally used non-equilibrium techniques. The comparison is based on the identification of the metastable phases produced by their specific electrical and superconducting properties. It is concluded that low temperature heavy ion bombardment is comparable with vapor quenching whereas laser quenching yields results similar to liquid quenching. Finally, the interesting superconducting properties of these rapidly quenched metastable alloys are discussed.
