초록
A new High Frequency Induction Heating (HFIH) process has been developed to fabricate dense Al2O3 reinforced with Fe-Ni magnetic metal dispersion particles. The process is based on the reduction of metal oxide particles immediately prior to sintering. The synthesized Al2O3/Fe-Ni nanocomposite powders were formed directly from the selective reduction of metal oxide powders, such as NiO and Fe2O3. Dense Al2O3/Fe-Ni nanocomposite was fabricated using the HFIH method with an extremely high heating rate of 2000oC/min. Phase identification and microstructure of nanocomposite powders and sintered specimens were determined by X-ray diffraction and SEM and TEM, respectively. Vickers hardness experiment were performed to investigate the mechanical properties of the Al2O3/Fe-Ni nanocomposite.
