High-Speed Interaction of a Metal Jet with Ceramics

Abstract

The destabilization of a cumulative jet with an initial velocity of more than 8 km/s upon penetration into brittle materials is studied. Using electron microscopy, the state of materials that remain in the cavity is analyzed. The observed phase transformations of copper and brittle materials in the residual cavity indicate high temperatures in the penetration region and reveal the effect of the thermodynamic parameters of the interacting materials on the destabilization of high-speed penetration.
