“…The successive accumulation and interaction of dislocation cause a reduction in the crystallite size and the lattice parameter decreased with milling time. Such variation in the lattice parameter of FeAl powders was observed by Hamlati et al[2], Fan et al[17] and Baris et al[18] and was attributed to the ordered structure as reported by Chan[19]. So, it can be concluded that elemental Fe and Al are alloyed to form slightly ordered bcc-Fe(Al) after 20 h milling, consistent with ordered phase.No obvious change is observed from the XRD patterns of powders milled for longer time and the lattice reached a steady value of 0.28649(1) Å.…”

“…In addition, the increasing complexity of these applications has resulted in the design of new nanomaterials and thus, the design/invention of new generation of nanoparticles. For this reason, an intensive research is still in development, particularly on the relationship between microstructure and magnetic response of these nanostructured alloys [2,3,4].…”

“…Finally, after 240 minutes of milling, all elements dissolved in Fe and a single phase supersaturated solid solution of Fe (BCC) formed. It is worth noting that in other similar Fe base alloys obtained by mechanical alloying, the formation of solid solution has been confirmed by Ding et al [12], Hamlati et al [13] and Hamzaoui [14]. Figure 3 displays the calculated crystallite size and lattice strain as a function of milling time.…”

FeNiCo base powder alloy with nominal composition Fe-27Ni-17Co-4Ti (wt%) was prepared from elemental powders by mechanical alloying. The structure of milled powders was characterized by XRD and SEM. The effect of nanosize structure on magnetic properties and shape memory behavior was studied using VSM and DSC. After milling for 240 minutes by high energy vibrational ball mill under argon atmosphere, supersaturated solid solution formed with mean crystallite size of ∼20 nm. Results of VSM examinations showed that by milling for 240 minutes saturation magnetization and intrinsic coercivity reached 304 emu/gr and 21 Oe, respectively. XRD analyses made it clear that transformation from BCC to FCC phase has occurred after annealing supersaturated milled powder at 650°C for 60 minutes. DSC curves indicated that martensite transformation in this alloy was suppressed due to refinement of the microstructure.

“…These results, detected after 4 hours of milling, are comparable to those reported for the majority of alloys based on iron [33,24]. This can be explained that the solubility of Al and Mg is limited in the Fe lattice but beyond 4 h. We notice a gradual increase in these parameters and this behaviour can be attributed to the diffusion of Al and/or Mg atoms in the iron lattice, because the atomic radii of Al (0.142 nm) and Mg (0.141 nm) are larger than that of Fe (0.123 nm) [34][35][36]. The formation of substitutional solid solution of Fe (Al, Mg) will be substituted by aluminium and magnesium in the iron matrix.…”

The mechanical alloying process has been used to synthesise the nanocrystalline Fe60Al35Mg5 ( wt % )powders in a high energy planetary ball-mill Retsch PM 400. The evolution structural, microstructural, morphological and magnetic properties of ball-milled powders at different milling times (t variation from 0 to 32 h) were investigated by X-ray diffraction using the MAUD program which is based on the Rietveld method, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) and the vibrating sample magnetometer (VSM). The XRD results reveal the formation of a bcc-Fe (Al, Mg) solid solution after 8 h of milling possessing a lattice parameter of 0,2895nm after 32 h of milling. It is also observed a refinement of the grain size which reaches 18,75 nm, and an increase in the microstrain after 32 hours of milling. Morphological evolution of the powder particles of the preceding mixture with the increase of the milling time, shows the coexistence of larger and fine particles at the beginning of the milling process linked to the competition of the phenomena of fractures and welding. A more or less homogeneous distribution of the particle shape is observed after 32 hours of milling. The elemental maps of Fe , Al and Mg done with EDX experiments confirmed the results found by XRD about the evolution of the alloy formation. Magnetic measurements of the milled Fe60Al35Mg5 ( wt % ) powder mixture exhibit a soft ferromagnetic character where the magnetic parameters are found to be very sensitive to the milling time mainly due to the particle size refinement as well as the formation of the solid solutions. After 32 hours of milling, the evolution of the saturation magnetisation (MS), coercive field (HC) remanent magnetisation (Mr) and squareness ratio (Mr/Ms) derived from the hysteresis curves are discussed as a function of milling time.
