Аннотация: Physical aspects of explosive compaction of alumina nanopowders with different phase compositions are studied experimentally. Physical processes that occur during consolidation of nanoparticles under pulsed loading are considered. Conditions of retaining of the material nanostructure after compaction and subsequent low-temperature Показать полностьюsintering are determined. Physicomechanical properties of explosive compacts and ceramics on the basis of these compacts are studied. A ceramic material characterized by a nanostructure (grain size of a parts per thousand 200 nm) and high values of density (97% of the theoretical value) and microhardness (up to 23.5 GPa) is obtained.
