Abstract
By means of automated electron backscatter diffraction(EBSD) analysis, we studied the local orientations of embeddedY2BaCuO5(211) particles withinmelt-textured YBa2Cu3Ox (YBCO) samples. On both components, we obtained high-quality Kikuchi patterns, thusallowing the automated mapping of the crystal orientations and a two-phase analysis of thesamples. Investigations were performed on a variety of melt-textured YBCO samples. Inmelt-textured YBCO with (001) orientation, we find that the embedded 211 particles donot have any preferred orientation. The EBSD maps also reveal that at certain orientationsof the 211 particles the YBCO growth is not altered. From the obtained EBSD mappings,we can conclude that the formation of small 211 particles will not disturb theYBCO matrix growth, whereas the presence of large 211 particles causes severechanges in the YBCO growth, leading to the formation of subgrains. The EBSDresults are presented in the form of local orientation maps and local pole figures.
