| Popis: | Results of in-situ diffraction experiments in the investigation of multifilamentary Bi-2223/Ag tape superconductors with neutron radiation are reported. The aim is to characterise the formation reaction of the Bi-2223 phase and the changes in the secondary phases assemblage under real reaction conditions without removing of the silver sheath of the composite. Furthermore, the mechanism of the evolution of a fibre texture of the superconducting phases Bi-2212 and Bi-2223 are discussed. Additionally, the results of the in-situ diffraction experiments will be related to the characterisation of the microstructure of quenched specimens done by scanning electron microscopy. Finally, a reaction model of the formation of the Bi-2223 phase within the composite conductor will be discussed. |
