摘要：
The microstructure and transport critical current of cold rolled, cold uniaxially pressed, and low load hot uniaxially pressed Ag-(Bi,Pb)(2)Sr2Ca2Cu3Ox tape has been investigated. The transverse and longitudinal transport current measurements show strong correlation with morphological non-uniformities induced by the cold deformation processes. The aim of low load hot uniaxial pressing is to increase the density of the ceramic core and reduce the anisotropic nature of the critical current induced during the cold deformation processes. The deformation mechanisms of the silver and ceramic core when under load have been studied, and a deformation mechanism map has been constructed. Experimental investigation of the low load region over a range of temperatures has been carried out.
