Summary

During green state processing of alumina matrix-Sic whisker composite materials, SiC whiskers develop a preferred orientation, or texture. The nature and degree of texture development is related to the green body processing technique and, for slurry processing techniques, processing variables such as, pH and solids loading. In this study, SiC whisker textures were quantitatively assessed using x-ray pole figure analysis of samples processed via dry pressing, slip casting, and pressure filtration. The results indicate that green state processing methodology significantly influences whisker textures in alumina matrix-SiC whisker composites (25 vol. %). It is important to examine whisker textures in these materials since whisker orientation directly affects fracture behavior.
