Dy2BaCuO5 distribution size in melt textured DyBa2Cu3Oy superconductors prepared by the horizontal Bridgman method

Back scattered electron micrographs were used to determine the size distribution of Dy2BaCuO5 after melt texturing. The size distribution was found to be non-uniform and it was concluded that the particles coarsened during the time which they spent in the liquid, and that they were pushed by the sol...

Description
Summary:Back scattered electron micrographs were used to determine the size distribution of Dy2BaCuO5 after melt texturing. The size distribution was found to be non-uniform and it was concluded that the particles coarsened during the time which they spent in the liquid, and that they were pushed by the solid-liquid growth front during the process. 36 refs.
