Notes:
In this paper we report a study using fully automated EBSP orientation measurements onthe texture and microstructure of fully processed Bi-2223 tapes produced by the powder-in-tubemethod. For the automated analysis a new unit cell describing the quasi-tetragonal Bi-2223 phase hasbeen developed. The texture data confirm that a strong fibre texture is produced during processing,with the c-axis of the Bi2223 plates parallel to the tape normal direction. Quantitative analysissuggests that the orientation density along the fibre texture is close to random. In contrast the distribution of misorientations shows significant correlations between the orientations, and is skewed towards low misorientation angles. A more detailed investigation reveals that the structure consists of colonies of plates, with low angle misorientations within each colony. Analysis of the rotation axes shows some differences as a function of misorientation angle
