摘要：

The introduction and refinement of the indentation technique has made the measurement of fracture toughness simpler. In this work, all Vickers indentations were positioned so that the Vickers-induced radial cracks developed along the same set of planes perpendicular to the (111) plane. The indented surfaces were examined by scanning electron microscopy (SEM). The Vickers indentation technique yields a fracture toughness value of 0. 53 MPa m** one-half plus or minus 0. 06 for monocrystalline germanium. 5 Refs.
