Unidirectional solidification of a melt, consisting of uranium dioxide and 5 to 15 percent by weight of tungsten, formed well-ordered arrangements of tungsten fibers or platelets in the uranium dioxide matrix. Fiber shape and orientation relations of the components indicate the development of several dominant growth modes.
