“…470 Contamination is often not quantified and is frequently excluded based on XRD measurements, which are not accurate because of the low intensity and considerable broadening of reflections and the high level of background scattering that characterises the XRD patterns of products obtained by milling. For example, Rahaei et al 386 did not observe the presence of iron by XRD during the synthesis of c-TiC using steel milling media, but the chemical quantification revealed iron contamination of 0.09, 0.28, 0.72 and 1.76 wt% after 1, 4, 8 and 16 h of milling, respectively.…”

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).

“…Mechanically induced self-propagating reactions (MSRs) are widely used for material synthesis but the mechanisms of these processes are not well understood [1][2][3][4][5][6]8,23,26]. In MSR, reactions induced by ball milling, the repeated mechanical action of the balls during the early stages of milling reportedly increases the temperature of the powders and the surrounding system without prior crystallization [2,[5][6][7].…”

“…It is suggested that the temperature at the electric power of 120 W was appropriate for the formation of Ti 2 AlC; for this alloy; and was high enough to cause the ¢ phase of the metastable beta alloy become more stable than the ¡ phase. 29,30) Peaks of TiC and VC are very close because these phases have the same space group of FM-3M and very close lattice parameter; a µ 0.43 nm for TiC 31,32) and a µ 0.42 nm for VC. 33) XRD spectra for uncarburized Ti-38Al and the alloy carburized at 120, 140, 160 and 180 W are shown in Fig.…”

Tribological behavior of Ti-5Al-2.5Sn, Ti-10V-2Fe-3Al and Ti-38Al carburized via current heating technique with graphite powders was studied. In carburizing, the direct current was applied across the graphite powders and alloys with a fixed electric power from 120 to 180 W for 20 min in argon atmosphere. The alloys were characterized using XRD, SEM, and hardness tester. Tribological behavior of the alloys was examined by pin-on-disk tribological test. Formation of TiC, TiC with VC and Ti 2 AlC with TiC on Ti-5Al-2.5Sn, Ti-10V-2Fe-3Al and Ti-38Al, respectively, could improve surface hardness and reduce friction coefficient leading to improve wear resistance of the alloys. Coatings of TiC totally exhibited higher wear resistance than that of Ti 2 AlC. Improvement of wear resistance was influenced by quality of coatings which could be sorted in descending as TiC, TiC with VC and Ti 2 AlC with TiC in the carburized Ti-5Al-2.5Sn, Ti-10V-2Fe-3Al and Ti-38Al, respectively.
