Melt-textured YBCO samples with embedded nanosize particles of Y2Ba4CuNbOx (Nb-2411) have been studied by means of electron backscatter diffraction (EBSD). The microstructure of these samples shows some distinct and unusual features, not observed in melt-textured bulk samples of other compositions. The resulting texture of the superconducting YBCO matrix is found to be excellent. Y2BaCuO5 (Y-211) particles, which are also present in these samples, exhibit no preferred orientation, as is the case generally in melt-textured YBCO samples. The embedded Y2Ba4CuNbOx particles, in contrast, exhibit only one orientation within the YBCO matrix. Furthermore, we find in the bulk pellets distinct areas with a high second phase particle concentration, adjacent to regions without secondary phase particles.
