“…Since they have the ability to provide vibration at high energy, they have an obvious potential to input sustained stress onto a sample surface, which induces the grains to refine to the nano-scale. There are a great number of studies that describe the Spex mill used in surface nanocrystallization process [ 7 , 12 , 27 ]. In order to prevent the incorporation of iron pollution products into the sample surface, the cylindrical container of the Spex mill was made from Ti-6Al-4V alloy.…”

In this paper, a nanocrystalline surface layer without impurities was fabricated on Ti-6Al-4V alloy by means of surface mechanical attrition treatment (SMAT). The grain size in the nanocrystalline layer is about 10 nm and grain morphology displays a random crystallographic orientation distribution. Subsequently, the low-temperature boriding behaviors (at 600 °C) of the SMAT sample, including the phase composition, microstructure, micro-hardness, and brittleness, were investigated in comparison with those of coarse-grained sample borided at 1100 °C. The results showed that the boriding kinetics could be significantly enhanced by SMAT, resulting in the formation of a nano-structured boride layers on Ti-6Al-4V alloy at lower temperature. Compared to the coarse-grained boriding sample, the SMAT boriding sample exhibits a similar hardness value, but improved surface toughness. The satisfactory surface toughness may be attributed to the boriding treatment that was carried out at lower temperature.

“…No correlation could be found, being in accordance with the data from the pioneering work 26 and for the one introducing the reagents melting temperature difference theory. 47,48 Takacs in his review also mentions that in most cases, little connection is found between the ignition time and Δ H / C p and supports the theory that the mechanical properties are important, 46 which is in alignment with trends observed for the bulk modulus in Fig. 5b.…”

“…The other perspective, being the investigation of different systems under the same milling conditions, is rare, namely when the inuence of various properties of the reagents and thermodynamics are considered. Some factors, including the thermodynamic ones, are tackled in the reviews by Takacs, 20,46 or more recently in the work of Ebrahimi-Kahrizsangi, 47,48 where the inuence of melting temperature of reagents is investigated in detail. Particularly for MCs, Tschakarov has proposed that there is a clear relationship between hardness of the reagents and the ignition time.…”

Due to the constant need for metal matrix nanocomposites (MMNCs), which are used in industrial applications such as automotive, aerospace, and many others, and therefore many researchers, are interested in making them nanocomposites with better performance, studies are continuing to improve their properties. In contrast to other versatile conventional production methods, powder metallurgy (PM) method is highly effective in eliminating porosity, wetting and casting defects. In this review, an in-depth discussion of the different MMNCs fabricated by the PM method with an explanation of the different stages of preparation of these nanocomposites such as powder production, pressing and sintering was discussed. Also, the different factors affecting milling and sintering processes were reviewed. Finally, the advantages, disadvantages, and more common applications of PM in the preparation of these nanocomposites mentioned above were discussed in some detail.
