| Popis: | This paper presents the results of metallographic analysis of the melting of S1 lead under shock-wave loading and unloading. Lead samples in a titanium capsule were loaded by a plane shock wave using an aluminum impactor 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 treatment 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. |
