摘要：
The results of measurements of shock compression wave profiles for three modifications of carbide ceramics in the stress range 3–19 GPa are presented. The dynamic elasticity and spall strength limits of the materials are determined. It is shown that these characteristics are sensitive to specific characteristics of reaction-sintered ceramics related to technological parameters of the process of their manufacturing. It is confirmed that the spall strength of highly rigid ceramics varies nonmonotonically with increasing compression stress in the shock wave.
