AIP Conference Proceedings, 2016
Electroexplosive Al/AlN nanopowder is used to synthesize low-dimensional particles of aluminum oxide and hydroxide phases with different shape, size, phase composition, and textural characteristics. It is shown that various conditions of production allow a synthesis of agglomerates of crumpled pseudoboehmite nanosheets, boehmite nanoplatelets, and ...

Journal of Materials Science, 2004
New nanostructured Al matrix composite Al-Al2O3 with homogeneous distribution of oxide particles was fabricated by magnetic pulsed compaction of partially oxidized Al nanopowders preheated up to 400-500°C in vacuum. The particles of starting powders with the mean sizes of 50-200 nm represent the grains of metal aluminum covered with the shells from ...
