Abstract:
This paper describes the structural studies of hollow cylindrical shells made of D16 and AMts aluminum alloys, loaded by sliding detonation. Explosive loading conditions for the complete convergence and closure of shells are established. Light optics scanning electron microscopy, and transmission electron microscopy are applied to study the structural and phase transformations in shells under shock-wave loading. The relation of composition, structure, and mechanical characteristics of alloys with their behavior under the action of shock loading is shown. There are several scenarios of convergence of shells, depending on their composition and loading conditions – from complete and steady convergence to multiple spalling.
Keywords:
aluminum alloy, shell, shock wave, transmission electron microscopy, microhardness, strengthening, recrystallization.
