Summary

Sialon matrix composites reinforced with SiC whiskers were hot pressed with various levels of yttrium aluminum garnet (YAG) as a sintering aid. The YAG content affected the amounts of liquid phases present during fabrication. It was determined that some liquid phase is required to achieve high density composites. However, at high sintering aid levels, degradation of the matrix-whisker interface occurs and the composite fracture toughness is reduced.
