The aim of this review article on recent developments of mechanochemistry (nowadays established as a part of chemistry) is to provide a comprehensive overview of advances achieved in the field of atomistic processes, phase transformations, simple and multicomponent nanosystems and peculiarities of mechanochemical reactions. Industrial aspects with successful penetration into fields like materials engineering, heterogeneous catalysis and extractive metallurgy are also reviewed. The hallmarks of mechanochemistry include influencing reactivity of solids by the presence of solid-state defects, interphases and relaxation phenomena, enabling processes to take place under non-equilibrium conditions, creating a well-crystallized core of nanoparticles with disordered near-surface shell regions and performing simple dry time-convenient one-step syntheses. Underlying these hallmarks are technological consequences like preparing new nanomaterials with the desired properties or producing these materials in a reproducible way with high yield and under simple and easy operating conditions. The last but not least hallmark is enabling work under environmentally friendly and essentially waste-free conditions (822 references).

“…Aside from the various synthesis methods, proper reinforcement plays a critical role in fabricating the composite with desired properties. The effect of different reinforcement elements such as Al2O3 [7], TiO2, ZrO2 [15], and TaC [16] on the MMCs, especially copper-based ones, have been studied widely. Investigating the additional amount of B4C revealed improvements in both wear resistance and hardness [17].…”

In this paper, the synthesis of the copper matrix nanocomposite and the effect of adding TiB2 nanoparticles on the copper matrix was investigated. Three different amounts of TiB2 nanoparticles 5, 10, and 15 wt% were added and sintering was carried out at 900 oC for 4 hours under argon atmosphere. The phase formation of achieved nanocomposites was studied by X-ray diffractometer and the morphology of the synthesized samples was studied by field emission scanning electron microscopy and atomic force microscopy. The polarization and electrochemical impedance spectroscopy (EIS) at 3.5 wt% NaCl solution at room temperature was were carried out to evaluate the corrosion behavior of synthesized samples. Results show that adding the TiB2 nanoparticles decrease the corrosion resistance by the formation of galvanic couples, but the effect of amounts of porosities on the corrosion resistance is higher. It is revealed that the variation of the surface roughness is in direct relation to the value of polarization current density.

TaC carbides are among the most efficient particles for reinforcing cast refractory alloys and superalloys against mechanical stresses at temperature as high as 1000°C and over. The most common TaC-strengthened superalloys contain less than 0.5 wt.%C and 5wt.%Ta. Enriching alloys in C and Ta may lead to higher fractions in TaC and therefore possibly to higher mechanical properties for service in hot conditions. The present work explores the microstructures achievable in a cobalt alloy, a nickel one and an iron one, by the introduction of 1 wt.%C and 15wt.%Ta, first using thermodynamic calculations and second by real elaboration. High fractions in TaC were effectively obtained, script-like eutectic ones, but also blocky preeutectic ones less efficient for reinforcement. These blocky TaC, the formation of which was explained by thermodynamic calculations, tend to aggregate together in some locations, with an overconsumption of Ta. However, some disagreements were noticed between predictions with thermodynamic calculations and as-cast microstructures.
