Pulsed current activated synthesis and consolidation of nanostructured MoSi2–TaSi2 composite

Pulsed current activated synthesis and consolidation of nanostructured MoSi2–TaSi2 composite Nanopowders of Mo, Ta, and Si were fabricated by high-energy ball milling. A dense nanostructured MoSi2–TaSi2 composite was simultaneously synthesized and sintered by the pulsed current activated heating method within 5 min from mechanically activated powder of Mo, Ta, and Si. A highly-dense MoSi2–TaSi2 composite was produced under simultaneous application of an 80-MPa pressure and the pulsed current. The sintering behavior, mechanical properties, and microstructure of the composite were investigated. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Nanopowders of Mo, Ta, and Si were fabricated by high-energy ball milling. A dense nanostructured MoSi2–TaSi2 composite was simultaneously synthesized and sintered by the pulsed current activated heating method within 5 min from mechanically activated powder of Mo, Ta, and Si. A highly-dense MoSi2–TaSi2 composite was produced under simultaneous application of an 80-MPa pressure and the pulsed current. The sintering behavior, mechanical properties, and microstructure of the composite were investigated.
