ABSTRACT:
A class of structural oxidation resistant ceramic base materials are described. The materials consist of an oxide matrix, which is resistant to the transport of oxygen by diffusion, and this matrix contains metallic fibers of a material which develops a stable protective oxide layer. The overall material composition is approximately eutectic so that the fiber-matrix combination can be formed by solidification directly from the melt. Directional solidification may be employed to produce a structure with oriented fibers.
