The Role of Graphene Admixtures in the Stability of Aluminum Oxide to Brittle Fracture under Pulsed Electrophysical Actions

Abstract

Abstract: We report the results of testing the dynamic strength of Al2O3 nanoceramics with different concentrations of five-layer graphene under the action of a high-current nanosecond electron beam and a high-voltage electric discharge of the same nanosecond duration. It is found that, under pulsed loading, an increase in the graphene content in the composite increases the brittleness of the nanocomposite.
