Textures in Ceramic Superconductors [PDF]

Texture, Stress, and Microstructure, 1990
Textures in bulk Y–Ba–Cu–O superconducting materials were studied. Texturing methods are based on the paramagnetic anisotropy, grain‐dimension anisotropy and surface‐energy anisotropy of the crystals. Five incomplete X‐ray pole figures including four superimposed ones were measured for the ODF calculation.
