Popis: |
Crack tip geometries in covalent crystals were studied by high resolution (HR) TEM. The materials used in the study were SiC, Si crystals and 15R-sialon grain. Cracks were introduced by Vickers indentation in SiC and Si. In 15R-sialon, crack was naturally introduced. It was found that the crack tips were atomically sharp and there was no macroscopic yielding zone. The results of TEM observation are summarized here. |
