“…For example, the wear properties of ECAP-processed Al-2, 3 and 5%Cu alloys under dry sliding conditions using different sliding distances and loads were investigated [26]. This study showed an increase in the microhardness with an increase in the number of ECAP passes and the Cu content ( Fig.…”

“…A number of studies have shown improved wear resistance when ECAP is used to produce UFG structures [26][27][28][29][30][31][32][33]. For example, the wear properties of ECAP-processed Al-2, 3 and 5%Cu alloys under dry sliding conditions using different sliding distances and loads were investigated [26].…”

Processing by severe plastic deformation (SPD) has been developed extensively over the last two decades in order to produce ultrafine-grained (UFG) materials having submicrometre or nanometre grain sizes. An important material property for UFG materials is good wear resistance so that they may be used in a range of structural applications. An examination of the published data shows that only limited reports are available to date on the wear behaviour of SPD-processed materials and, furthermore, many of these results appear to be conflicting. The correlation of hardness and wear is limited because the wear property is a system property that in practice is influenced by a range of factors. Accordingly, this review is designed to examine recent reports related to the wear resistance of materials processed by SPD with particular emphasis on alloys processed using equal-channel angular pressing (ECAP), high-pressure torsion (HPT) and accumulative roll-bonding (ARB).

“…The extensometer with base length of 10 mm was mounted on the middle part of sample with minimal cross-section. For additional ECAP-processed microstructure improvements, the HCV deformation [13][14][15] technique was used on the materials testing system Instron-8516. The all materials were studied under tension/compression cyclic loading at strain amplitudes ranging from ±0.05, ±0.2, ±0.5, ±1, and ±1.5 % at a low frequency of 0.5Hz for 20 cycles, respectively.…”

“…Nevertheless, it is clear that for the fabrication of advanced installations for electrical conduction from Cu-Cr alloys use, there is a need to produce an UFG or NC microstructure with high electrical conduction properties and suitable high wear resistance (WR) and low coefficient of friction (COF) at temperature increase. To date, the tribological properties of UFG Cu [12], Al-Cu alloys [13], pure Ti [14] and hard coatings [15], etc. have been studied.…”
