Hyperfine fields and magnetoelastic surface effects in Fe72Cu1.5Nb4Si13.5B9 nanocrystalline alloy
(Institute of Nuclear Chemistry and Technology, 2003)
In this work hyperfine fields of two-phase nanocrystalline Fe72Cu1.5Nb4Si13.5B9 alloys were studied in order to verify the existence of surface effects. To obtain a series of nanocrystalline samples with small grains of ...
Mössbauer study of a Fe–Zr–B–Cu–(Ge, Co) nanocrystalline alloy series
Amorphous and nanocrystalline Fe–Zr–B–Cu alloys with partial substitution of Co for Fe and Ge for B have been studied by Mössbauer spectrometry (MS). The compositional and microstructural dependence of the different hyperfine ...
Extracting the composition of nanocrystals of mechanically alloyed systems using Mössbauer spectroscopy
Determining the composition at the nanoscale generally requires the use of experimental techniques such as 3D atom probe or nanoanalysis, which have limited availability, involve high economic cost and, moreover, imply ...
Evolution of Fe environments in mechanically alloyed Fe–Nb–(B) compositions
Nanocrystalline alloys of nominal composition Fe85Nb5B10 were produced by mechanical alloying from a mixture of elemental powders. Two commercial boron structures were used: amorphous and crystalline. In addition, a third ...
Influence of Milling Time on the Homogeneity and Magnetism of a Fe70Zr30 Partially Amorphous Alloy: Distribution of Curie Temperatures
In this work, the mechanically alloyed Fe70Zr30 (at. %) composition has been used to study the influence of milling time on its homogeneity and magnetic properties. The microstructure and Fe environment results show the ...
Mechanical Amorphization and Recrystallization of Mn-Co(Fe)-Ge(Si) Compositions
Mechanical alloying using a planetary ball mill allowed us to obtain two homogeneous systems formed by units with nanometer size and MnCo0.8Fe0.2Ge1−xSix stoichiometry (x = 0 and 0.5). The phase evolution of the systems ...
