“…This suggests the occurrence of WMoC-NiC decomposition. Previously, we prepared the same system under different synthesis conditions, and this kind of decomposition was not observed [26,27], indicating that the crystal deformation conditions used in this work, namely 180 h of milling, followed by sintering, heat treatment, and quenching, supply the energy for the decomposition of the milled phases and therefore the formation of new phases during sintering and quenching. Table 1 summarizes the crystallographic data of the phases obtained by mechanical milling and quenching.…”

In the present work, the synthesis and decomposition of low-dimensional materials from a Ni15Mo25W10C50 system produced by mechanical alloying was reported. During the milling process, the resultant phases were WMoC and NiC, and after sintering and quenching, MoNi3, WMo, Ni4W, WC, MoNi and Mo2C were found. The samples were analyzed by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Nanotubes with the lengths ranging from 500 nm to 2 μm, spheres and novelty globular particles with sizes ranging from 40 to 600 nm as well as “petal-like” estructure were observed. The results revealed the formation of a microstructure with morphology similar to spinodal decomposition followed by a sequence of invariant reactions leading the production of modulated and novel branched structures. We proposes a theoretical mechanism of formation that is associated with the modulated structure observed after quenching.

“…after the sintering process, and a comparison with its respective theoretical density (ρ t ) was also showed. In addition, the porosity can also be associated with the milling process as is explained in the literature [31]. ey reported from the BET results that the surface area of the samples is strongly dependent on the mechanical milling method [31].…”

Mechanical ball milling assisted by sintering in the solid state was used in this research to produce the Zn-Ni x system alloy. e derivative powder compositions of Zn-Ni x (x 0, 5, 10, 15, and 20 wt.%) were obtained to study the Ni e ects on the microstructural and mechanical properties. It is worth remarking that conventional methods are not appropriate for the manufacture of the Zn-Ni x system alloy. e morphological structure and phases were examined by optical microscopy, X-ray di raction, and SEM/EDS elemental mapping, whereas the mechanical behavior was accomplished by means of a diamond indentation print (Hardness Vickers). e results showed that the intermetallic γ-ZnNi phase did not form during milling time (<4 h); it appears after the sintering process, which is associated with atomic di usion mechanism through grain boundary at the minimum interfacial energy (ΔG256°C −13.83 kJ·mol −1).e powder Zn-Ni 10 was found to have better properties. Semispherical coarser particles were seen into the metal matrix (Zn δ-hcp structure) as segregates; however, each particle contains an intermetallic compound Zn-Ni that encloses the Ni (α-fcc structure) pure phase.e Ni-α phase was then transformed into a γ-ZnNi intermetallic compound which shifts to higher values of mechanical hardness from about 60 HV to 400 HV units.
