Texture analysis of monofilamentary, Ag-sheathed (Pb,Bi)₂Sr₂Ca₂Cu₃O _x tapes by electron backscatter diffraction (EBSD)

Using automated orientation imaging, the grain orientations and texture of monofilamentary, Ag-sheathed (Pb,Bi)₂Sr₂Ca₂Cu₃O _x (Bi-2223) tape is analysed in detail by means of electron backscatter diffraction (EBSD). The achieved high image quality of the Kikuchi patterns enables multi-phase scans including Bi-2223, Bi₂Sr₂CaCu₂O_x, Bi₂Sr₂CuO_x, (Sr,Ca)₁₄Cu₂₄O₄₁ and Ag to be performed. Two areas are selected for the EBSD analysis, one close to the silver sheath, the other located in the center of the sample. The grain orientation maps are presented for each phase separately allowing a new insight into the microtexture of Ag-sheathed Bi-2223 tapes. Furthermore, the EBSD analysis provides the possibility for a misorientation angle analysis within each individual phase.
