Structural analyses and investigations of flux penetration of typically melt-textured YBa2Cu3O7-δ samples were performed. This allows regions of suppressed critical current density to be directly related to microstructural defects. At small-angle grain boundaries the critical current density was found to be reduced by a factor of up to 20.
