摘要：

The crack systems associated with room-temperature Vickers indentations on {001} surfaces in 9.4-mol%-Y2O3-stabilized cubic ZrO2 single crystals are examined. The indentation-induced radial cracks are not always perpendicular to the free surface, as is usually assumed, and the surface traces are therefore not a reliable guide to the nature of the cracking. In fact, indentations with [100] diagonals do not form cracks on {010}, but form secondary radial cracks on inclined planes and noncoplanar median cracks on (110) or (110BAR).
