Summary

The slow crack growth properties of an Al2OO3/SiC whisker composite have been evaluated using indented specimens in a dynamic fatigue experiment. The composite has a significantly higher resistance to slow crack growth compared to a fine grained Al203 material as indicated by the relative values of the slow crack growth parameter, n. The slow crack growth regions were intergranular in both cases implying that the matrix-whisker interface plays an important role in determining the slow crack growth properties of the composite.
