Electrical resistivity measurements have been performed for annealed Cu–Sn wires with compositions of 2, 5, 10 and 13.5 wt% Sn from room temperature to 700 °C. The annealing behaviour of cold-worked samples of these compositions has been investiga

The bronze process for the fabrication of niobium-tin superconductors is a mature and successful technology, but the optimisation of these conductors still requires a timeconsuming trial-and-error approach. The choice of heat treatment influences not

We report about the improvements on overall critical current density j/sub e/, long-length processing, mechanical properties, and insulation. These topics are discussed for Bi-2223/Ag-alloy tapes for typical DC-applications, for AC-applications which

Progress in developing long-length YBCO coated conductors (CC) with high critical currents, up to almost 500 A per cm-width, is reported. Coated tapes based on commercial quality stainless steel substrates are manufactured employing a HR-PLD-YBCO tog

In the past (Bi,Pb)/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub x/ Ag/Ag-alloy-sheathed High-Temperature Superconductor (HTS) tapes (Bi-2223 tapes) have been proven being suitable for building quite different system components for a variety of application

We show some of the results of production and development of silver-alloy sheathed high temperature superconducting Bi-2223 tapes for applications in power engineering and high magnetic fields (at low temperatures). Depending on the special applicati

For the use of silver or silver-alloyed Bi-2223 tapes in different applications of power engineering, very good electrical and mechanical properties are required. Besides high critical current densities of up to 100 kA/cm/sup 2/ the tapes have to cop

Multi-stage evaporation is a well-established method for the controlled growth of chalcopyrite thin films. To apply this technique to the deposition of Cu2ZnSnS4 thin films we investigated two different stage sequences: (A) using Cu2SnS3 as precursor

The thermal expansion properties of polycrystalline Bi2Sr2Ca1Cu2O8+x melt-processed bulk specimens, and Bi2Sr2Ca1Cu2O8+x monocore as well as multifilamentary round wires in Ag or Ag-alloy matrix have been investigated over the temperature range from
