Abstract
Zone melting has been used to produce texture in extruded YBa2Cu3O6+x wires. Highly aligned microstructures are produced with a‐b planes oriented along the axis of the wires. Microstructural observations show that changes in alignment orientation can occur, and can result in the inability to carry a transport current. Pulsed transport Jc measurements on oriented samples indicate a zero field critical current density greater than 4×104 A/cm2.Keywords
