“…12.5 Mn 42.5 Al 45.0 , and the saturation magnetization is 380 G/cc and 400 G/cc, respectively, in a field of 15 kOe. The origin of the ferromagnetism in these alloys has been ascribed to the FM exchanges between Mn atoms, unlike the observed behavior in other MnAl-based [6][7][8][9]. Since the physical properties of these materials are strongly dependent upon composition, in this contribution we investigate effects of the iron content on the magnetic properties of the Mn 1−x Al 1−y Fe x+y compounds.…”

[16] Second, the dense packing may be favorable for the development of the magnetizations, although both the presence of the large X atoms and the trend toward antiferromagnetic exchange coupling in dense-packed Fe systems [2] has the opposite effect.…”

First principle calculations are used to investigate the intrinsic magnetic properties of intermetallic alloys of the type XMn, where X is a 4d or 5d element and M is Fe or Co. Emphasis is on the hexagonal C14 Laves-phase 1:2 and 1:5 alloys, the latter crystallizing in the CaCu5 structure. These series are of interest in permanent magnetism from fundamental and practical viewpoints, respectively. In the former, the unit cells form a prototypical motif where a heavy atom with high spin-orbit coupling and magnetocrystalline anisotropy is surrounded by many somewhat smaller M atoms with high magnetization, and the latter are Laves-phase derivatives of renewed interest in permanent magnetism. Our DFT calculations predict magnetic moments, magnetizations and anisotropies, as well as formation energies. The results are analyzed across the 4d and 5d series, especially with respect to hybridization effects between 3d and 4d/5d bands.

“…Studying Fe-Nb binary system alloys via the MA process is important because it can provide alternative processes, like viable results for better understanding the system phase equilibrium, and for many alloy families based on Fe-Nb 8,9 . Some works have detailed this [10][11][12][13][14][15][16][17][18][19] . Most studies on Fe-Nb systems 10,12,13,[15][16][17][18] deal with systemically studying phase amorphization modes via the MA process, using milling times varying from 30 minutes to 70 hours.…”

“…Vélez et al [15][16][17] published three works related to obtaining Fe-Nb alloys via MA, based on magnetic property studies that used two heat treatments seeking LAVES (Fe 2 Nb) phase formation. Roy et al 14 , analyzed the magnetic behavior of the LAVES amorphous phase prepared via MA. They found that the phase had paramagnetic characteristics.…”

Effect of Process Control Agents on Fe-15at.%Nb powder during Mechanical Alloying

In this paper, Fe-15at.%Nb alloys were produced from high purity Fe (min. 99.8%) and Nb (min. 99.8%) powders via a mechanical alloying process. The effects of different Process Control Agents (i.e., methanol, hexane, and stearic acid) were investigated with powder morphologies, particle size distribution, and phase formation, and were sampled after up to 80 milling hours at 350 rpm. The powder morphologies and particle sizes were evaluated using scanning electron microscopy and laser diffraction analysis, respectively, and phases were identified via X-ray powder diffractometry. The results demonstrate for all conditions that, in the early stages, there was significant particle agglomeration due to the ductile-ductile feature of Fe and Nb powders, and latter an amorphization trend up to 80 milling hours. Methanol was the most efficient Process Control Agent in terms of avoiding cold welding, reducing of agglomeration, particle size distribution, reducing contamination and crystallinity reduction rate.
