The destabilization of a cumulative jet with an initial velocity of more than 8 km / s when penetrated into brittle materials is studied. Using electron microscopy, the state of residual materials 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 influence of the thermodynamic parameters of interacting materials on the destabilization of high-speed penetration.
