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.

金属射流与陶瓷的高速相互作用

摘要

研究了初始速度超过8 km / s的累积射流在渗入脆性材料后的失稳情况。使用电子显微镜，可以分析残留在空腔中的材料的状态。在残留腔中观察到的铜和脆性材料的相变表明穿透区的高温，并揭示了相互作用材料的热力学参数对高速穿透稳定性的影响。
