摘要：

In this contribution, we apply orientation imaging microscopy (OIM) to melt-textured, bulk YBa2Cu3Oy (YBCO) samples, which require to perform an automated two-phase analysis. Both YBCO and the green phase Y2BaCuO5 (Y-211) are of orthorhombic crystal structures, but with clearly distinct unit cell parameters. We obtain the orientations of the individual crystallites and the misorientation distributions for both YBCO and Y-211. From the obtained data, we calculate the orientation distribution functions.
