The resistance and/or susceptibility to slow crack growth can be quantified by determining and comparing the slow crack growth parameter, n from Eq. 1, for each of these fibers. Two te.st techniques, which have been successfully used for glass and other ceramics (Wiederhorn, 1968 Evans, 1974), were applied for the AI2O2/Y3AI5O12 eutectic fibers to determine n and estimate ATp in Eq. 2.

Higher-magnification photo of the fracture mirror area and failure-initialing flaw wider bands of YjAlsOn (top right). Different morphologies have been observed along the fiber length. Two examples are shown at the bottom.

This clearly indicates that AI2O3/Y3AI5O12 eutectic fibers have superior slow crack growth resistance to (0001) AI2O3 fibers at these temperatures for these test durations. [Pg.119]
