This work synthesized and investigated the amorphous alloy Fe73Si22B5obtained by high-energy milling. The properties of the amorphous alloy Fe73Si22B5were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) with EDS, Fourier transform infrared spectrometry (FTIR), thermal analysis TGA/DTA, textural analysis by N2 (BET/BJH), and magnetic measurements (VSM). The results confirmed that the Fe73Si22B5alloy reached the desired amorphization degree and presented IV isotherms with a hysteresis loop for mesoporous materials. The TGA/DTA confirmed that Fe and Si ions are quickly oxidized in the environment with the mass slightly increased to 27.5%. The Fe73Si22B5exhibited soft magnetic properties with ferromagnetic characteristics. The FTIR spectra exhibit absorption peaks corresponding to the presence of (R)O–H, Fe–O, Si–O, O–Fe–O, and Si–O–Fe groups. This result suggests that the developed high-performance Fe73Si22B5amorphous alloy has great application potential in various research fields. |
