摘要：
Nanopowders of Fe0.54Cr0.18Al0.26Si0.016 and Al2O3 were synthesized from Fe2O3, Cr, Si, and Al powders using high-energy ball milling. Ahigh-density nanocrystalline 3.7Fe(0.54)Cr(0.18)Al(0.26)Si(0.016)-Al2O3 composite was consolidated with mechanically synthesized powders of Al2O3 and 3.7Fe(0.54)Cr(0.18)Al(0.26)Si(0.016)-Al2O3 through a pulsed current activated sintering (PCAS) method within 1 min. The hardness of the composite and the average grain sizes of Al2O3 and Fe0.54Cr0.18Al0.26Si0.016 were investigated. (C) 2011 Elsevier B. V. All rights reserved.
