Abstract
In this present study, the mechanical alloying technique was used to the amorphization of Al80Fe20 system. The particle size, the thermal behavior, and the magnetic properties were investigated on the milled specimens in the different milling times. The performed tests on the milled specimens included the X-ray diffraction (XRD), determine the magnetic properties, and the Differential scanning calorimetry (DSC). The results were shown that the milling time for the amorphization was 70 h, in this system. The peaks of DSC were demonstrated that the mechanical alloying caused to formation of the amorphous phase. It is noteworthy that increasing the milling time after 70 h caused to formation of the crystalline Al and Al3Fe phases. In addition, the amorphization of used alloy at 70 h caused to decreasing the residual magnetism to 0.11 T and improving the soft magnetic behavior.
