AB - We have applied mechanical alloying (MA) to produce soft magnetic composite material using a mixture of elemental Fe2O3-Mg powders. An optimal milling and heat treatment conditions to obtain soft magnetic α-Fe/MgO composite with fine microstructure were investigated by X-ray diffraction, differential scanning calorimetry (DSC) and vibrating sample magnetometer (VSM) measurement. It is found that α-Fe/MgO composite powders in which MgO is dispersed in α-Fe matrix are obtained by MA of Fe2O3 with Mg for 30 min. The saturation magnetization of ball-milled powders increases with increasing milling time and reaches to a maximum value of 69.5 emu/g after 5 h MA. The magnetic hardening due to the reduction of the α-Fe grain size by MA was also observed. Densification of the MA powders was performed in a spark plasma sintering (SPS) machine at 800~1000 o C under 60 MPa. X-ray diffraction result shows that the average grain size of α-Fe in α-Fe/MgO nanocomposite sintered at 800 o C is in the range of 110 nm.
