Abstract

Ninety six percent grain-orientation was achieved in YBa2Cu3O(7-x) ceramics using the hot-forging technique. X-ray diffraction measurements show that the c-axis is oriented parallel to the direction of pressing while the a and b axes are in the plane perpendicular to the pressing direction. Optical and electron microscopy fully support the X-ray results. Highly grain-oriented samples show a sharp Tc at 92 K and in some samples, Jc was found to be close to 10,000 A/sq cm.
