| 摘要 |
Methods for producing biaxially aligned superconducting ceramics are disclosed. The methods include fabricating a composite precursor formed of substantially planar filaments of a superconductor precursor surrounded by a matrix, and thermomechanically processing the precursor to texture at least the interfacial layers with the matrix without converting appreciable amounts of the composite precursor to the superconducting oxide to form a preliminary filament material. The method also includes reaction texturing the preliminary filament material to form and texture a superconducting oxide. Reaction texture involves first heating at relatively low oxygen pressure, then heating at higher oxygen pressure. |
