“…The alloys of the nominal composition of FeCuNbSiB, FeMBCu (M = Zr, Nb, Mo) were investigated. The methods like mass loss measurement, potentiometry, gravimetry, XRD and magnetic measurements have been employed to perform the corrosion analysis [1][2][3][4][5][6].…”

Nanocrystalline Fe-based alloys are interesting for their soft magnetic properties. Because these alloys are potentially applicable in outdoor-working components, their corrosion behaviour requires careful analysis. This work presents the results of the atmospheric corrosion tests in industrial and rural environments performed for up to 6 months. We compared the corrosion behaviour of two different compositions of NANOPERM-type alloys: FesT.hZr6.hB6 and Fe76MosCulBx5 with classical FINEMET alloys of the nominal composition of Fe73.5CulNb3Si13.5B9 type. The techniques of Mhssbauer spectroscopy, conversion electron M6ssbauer spectroscopy, X-ray diffraction and transmission electron microscopy have been employed to compare their corrosion rate, characterize corrosion products and inspect the structural changes of the nanocrystalline structure. It was found that the Si-containing FINEMET alloys are the most corrosion-resistant whereas worse corrosion properties were observed for molybdenum-containing Fe76 Mos Cul B15 alloy. The corrosion product formed on the surface of NANOPERM-type alloys showed a needlelike morphology and a poor crystalline order and has been identified as lepidocrocite, -~-FeOOH.PACS: 76.80. § 75.50.Cc

“…These alloys have attracted substantial attention due to their soft magnetic properties that indicate their importance in applications such as power transformers, data communication, interface components, electromagnetic interference prevention components, magnetic heads, sensor, magnetic shielding and reactors [66] . The effects of the composition, structure and magnetic properties of these materials have been extensively reported.…”

“…Since the amorphous precursors do not show (see Table 1) the above high values, it is necessary to grow enough of the crystalline bcc FeCo phase by an appropriate annealing. Such Hitperms also provide the opportunity to study the influence of MH on thermally stable soft-magnetic properties obtained at higher annealing temperatures ($600 1C) and without the effect of suspect SiO 2 surface layers [6] if compared with Si-rich FeNbCuBSi Finemets.…”
