Magnetic Response of Powders to Shock Loading and Fabrication of Nanocrystalline Magnets

  • K. Kondo
Part of the High-Pressure Shock Compression of Condensed Matter book series (SHOCKWAVE)


Fabrication of materials of metastable phases and/or metastable microstructures is difficult using conventional sintering methods. This is because the conventional processes are driven by the difference of chemical potential and are slow enough that recrystallization to stable phases and grain growth by means of mass transport can follow in the time afforded by the process. Shock-compaction techniques, on the other hand, can consolidate powders without recrystallization or grain growth under the optimum conditions in which only the surfaces of the powder particles fuse, solidify, and join each other within the brief duration of the shock loading, typically 1 μs [1–10].
