Pulse electric current sintering of alumina/nikel nanocomposites

Abstract

Typical magnetically functionalized Al2O3/Ni nanocomposite materials were fabricated by pulse electric current sintering process. The rapid densification and various microstructures were accomplished with controlling PECS temperature. The PECSed Al2O3/Ni system exhibited peculiar mechanical and magnetic properties with microstructure developments. The mechanical properties of Al2O3/Ni nanocomposite were optimized as controlling microstructures, and fine metal dispersion into the Al2O3 matrix give to the various ferromagnetic properties.
