Abstract
Binary pure powders Fe60 –Co40 (wt%) fabricated by powder metallurgy technology ,compacted at 10Mpa and heat treated at 850,950 and 1050℃ for (1hr)sintering time, then slow cooling to RT. The aim of this paper to study and characterize the effect of heat treatments on the structural , microstructural and magnetic properties using x-ray diffraction (XRD), Scanning Electron Microscopy(SEM)coupled with Energy Dispersive x-ray spectroscopy (EDX) and the Vibration Sample Magnetometer (VSM).The structural results show that two face centered cubic (FCC) for Fe and Co respectively ,with a third phase of hexagonal(HCP) for Co element are observed clearly at all treated temperatures. The composition of elements in the Fe60-Co40 alloy are also detected from EDX analysis. The SEM resulted morphology shows the aggregation as cluster of spherical particles size at 1050℃ . The magnetic properties are increasing significantly with increasing the heat treatment until 1050℃ and above that at 1150℃ treated ,dropped suddenly.
