T.E.M. investigations of room temperature microplasticity in MgAl2O 4 spinel
Year: 1979
Type: article
Abstract: Dislocations produced by room temperature Vickers indentation on a single crystal of MgO.1.1 Al2O3 spinel have been characterized by T.E.M. These dislocations belong to 1/2 < 110 > { 111 } glide systems. No trace of { 100 } nor { 110 } glide is found. Moreover these dislocations show no preferred orientation nor visible dissociation. However after annealing for 1 day at 1 000 °C, dissociations of the order of 100 Å are observed.
