Abstract
This paper presents the results of metallographic analysis of the melting of C1 lead under shock-wave loading and unloading. Loading of lead samples in a titanium capsule was carried out by a plane shock wave using an aluminum projectile 6 mm thick, which was accelerated by detonation products of an explosive. The results of metallographic analysis of samples in the initial state, subjected to heat treated under normal conditions, and recovered after shock-wave loading are given. Melting traces were found in lead after shock-wave loading by a pressure of 25.6 GPa and subsequent unloading.
