“…The bcc lattice parameter for this sample (Table I) is 0.2932 nm, which is larger than that for the Fe 65 Al 35 alloy (0.2920 nm in Reference 34) obtained in the same way and lies within the known data range for the Fe-Al system. [31,33] This result is consistent with that of a previous study, [12] in which the formation of a solid solution with a similar composition-Fe 60 A 35 Sn 5 -was studied. The authors of that study attribute the lattice parameter growth to atomic radii of the alloying elements (Al-0.142 nm and Sn-0.158 nm), which are larger than that of the Fe atom, and to an increase in the dislocation density at the grain boundaries.…”

“…A thermal study of nanostructured Fe 60 Al 35 Sn 5 alloy found that the endothermic peak at around 234°C corresponds to tin melting. [12] The DSC curve in Figure 5 for the current sample clearly shows that no peak could be assigned to free tin. Some peculiarities of the DSC curve can be interpreted by drawing on experience from thermal studies for binary Fe-Al alloys and ternary Fe 60 Al 35 Sn 5 alloy.…”

“…Some peculiarities of the DSC curve can be interpreted by drawing on experience from thermal studies for binary Fe-Al alloys and ternary Fe 60 Al 35 Sn 5 alloy. [12,44] A wide exothermic halo from 250°C to 450°C may account for the structure relaxation by elimination of the stress fields resulting from crystal defects and the exothermic peaks observed at T > 550°C may be ascribed to intermetallics' recrystallization and grain growth.…”

A nanostructured Fe 65 Al 30 Sn 5 alloy has been synthesized by mechanical alloying of elemental Fe, Al, and Sn powders in a planetary ball mill. The structure and phase composition of the asmilled sample and the samples after subsequent heat treatment at 400°C, 500°C, and 800°C were investigated using X-ray diffraction, electron microscopy, 57 Fe and 119m Sn Mo¨ssbauer spectroscopy. We found that the as-milled sample is a nanocrystalline ternary bcc solid solution of the estimated composition Fe 62 Al 32.6 Sn 5.4. The samples of Fe 65 Al 30 Sn 5 after annealing are non-uniform materials that mainly comprise the ternary B2 ordered phase Fe 65 Al 30 Sn x , x Sn ≤ 1 at. pct. In addition to the dominant B2 ordered phase, we also identified chemically non-ordered regions, Sn and FeSn, FeSn 2 .

“…After 100 h of milling, the particles become finer and more spherical (Figure 5h,i), signifying the completion of the solid-state amorphization. [17,18] Figure 7 shows the energy dispersive X-ray spectroscopy analysis (EDX) (attached to the SEM) elemental mapping of 120 h milled samples of Ni 70 Ti 10 B 20 .

The mechanochemical method of synthesizing nanomaterials is known for its simple alloying technique to produce quasicrystalline and amorphous alloy phases. [1] The most tangible benefit of this method is, it does not require any heat that may adversely cause physical and chemical changes in the materials. This makes it very suitable for the synthesis of many metal alloys and ceramic composites where the prevention of any undesirable heat-induced oxidation or degradation is necessary. By optimizing milling parameters like rotational speed, ball-to-powder ratio, milling media, milling time, and also in some cases, the addition of process controlling agents, a variety of materials can be synthesized utilizing this method. Mechanochemical or mechanical alloying (MA) method for synthesizing nanomaterials involves high-energy milling technique and is generally carried out under controlled atmosphere. The major drawbacks of this method, however, are: a) discrete nanoparticles in the finest size range are difficult to prepare, and b) risks of contaminating the product from the attrition of milling media. In this method, materials go through the process of fracturing, cold welding, flattening, and fragmenting. [2] Continuous fracturing and cold welding of the milling powders during the process leads to solid state reactions between the components to form ultrafine powders of alloyed materials. The particle size distributions can be controlled by changing the aforementioned milling parameters like rotation speed, milling time, etc., and eventually nanostructured powders can be achieved effectively. [3][4][5] The syntheses of Ni-Ti-B ternary alloys from their elemental stages are not very well studied for their alloyed phase compositions and related physicochemical and mechanical properties. MA is an alternative and cost-effective method for the synthesis of these alloys with respect to the other methods, such as melt and quench process.

“…The idea then emerges of trying to improve the characteristics of FeAl alloys by adding magnesium especially as this element has never been introduced in such alloy produced by MA. The objective is then to obtain a material with excellent corrosion resistance, more resistant to high temperatures, and in particular with more stable mechanical properties as a temperature function [23][24].…”

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.
