Effect of deformation of parameters on interface morphology of silver-sheathed high-temperature superconductor tapes

Journal Article


Abstract


  • We have produced a series of Ag sheathed BiSrCaCuO tapes with a systematical variation of some of the deformation parameters to investigate effects on the distortion of the sheath-core interface, which often shows a wavy morphology ("sausaging"). The increase of the powder density has been measured directly by monitoring the volume of the tapes during the deformation. Using silver particles as a "tracer", the non-uniform, wavy powder flow can be observed also inside the bulk oxide core. We develop a simple model of the deformation process, based on a relaxation concept, and compare its quantitative predictions with our experimental results and with those of other groups. © 1995.
