“…In this case, despite the increase in the wear rate during the accumulation of radiation damage in the near-surface layer, the wear rate remained comparable with similar wear rates for high-entropy alloys (TiZrNb)14AlMo and CoCrFeNiMn, the test results of which are presented in review [40]. Thus, by analyzing the data on changes in the tribological and strength characteristics of the studied NbTiVZr alloys depending on the irradiation fluence and the amount of accumulated radiation damage, we can draw the following conclusion.…”

The purpose of this paper was to study the kinetics of accumulation of radiation damage in the near-surface layer of a high-entropy NbTiVZr alloy upon irradiation with heavy Kr15+ ions and fluences of 1010–1015 ion/cm2. According to the data of X-ray diffraction analysis, it was found that irradiation with heavy ions lead to structural changes associated with the accumulation of deformation distortions and stresses. In this case, the nature of deformation distortions was associated with tensile distortions of the crystal lattice and swelling of the near-surface layer. An analysis of the strength properties of the irradiated samples showed that the accumulation of deformation distortions in the near-surface layer lead to a decrease in the resistance to cracking and destruction of the near-surface layer. In this case, the main changes occurred at fluences above 1013 ion/cm2, which are characterized by an excess of the threshold for overlapping defective regions that appear along the trajectory of incident ions. Tribological tests showed that an increase in defective inclusions in the structure of the near-surface layer lead to an increase in friction and a decrease in crack resistance.

“…The development of multicomponent solders requires extensive research since binary Sn-based solders can no longer keep up with the rapid pace of technological advancement. In the form of HEAs, multicomponent alloys have exceptional qualities, particularly in terms of creep [315], magnetic behavior [316], biocompatibility [317], wear [318], and slow diffusion effect [311]. The use of HEA solder may impart these special characteristics to TSV/solder interconnections, opening a new design space and expanding the uses of solder bumps.…”

Three-dimensional (3D) packaging using through-Si-via (TSV) is a key technique for achieving high-density integration, high-speed connectivity, and for downsizing of electronic devices. This paper describes recent developments in TSV fabrication and bonding methods in advanced 3D electronic packaging. In particular, the authors have overviewed the recent progress in the fabrication of TSV, various etching and functional layers, and conductive filling of TSVs, as well as bonding materials such as low-temperature nano-modified solders, transient liquid phase (TLP) bonding, Cu pillars, composite hybrids, and bump-free bonding, as well as the role of emerging high entropy alloy (HEA) solders in 3D microelectronic packaging. This paper serves as a guideline enumerating the current developments in 3D packaging that allow Si semiconductors to deliver improved performance and power efficiency.

“…Evolution of the BCC crystal structure in HEAs has been upheld to be a contributing factor to the enhancement of the friction and wear characteristics of high-entropy alloys. Among the crystal structures of HEAs, the BCC structure has a small atomic packing density of 68%, resistant to intra-crystalline dislocation, with profound strength, and hence, high-wear resistance [60]. To ensure the formation of the BCC lattice in HEAs, some elements must be incorporated, like Fe, V, Nb, W, Mo, Ta, and Cr [60,61].…”

High-entropy alloys (HEAs) are prospective advanced materials for the production of components that operate at high, severe friction and in high-temperature environments. This is because they possess unique properties requisite for such applications. Hence, this study was aimed at reviewing most recent publications on the tribological characteristics of HEAs processed with spark plasma sintering (SPS). The choice of SPS was because it impacts alloys with a homogenous microstructure, high wear resistance, densely packed grains, and nanocrystalline microstructure. The resource materials for this study were obtained from the Scopus-indexed journal/Google Scholar website for articles published within the last five years. From the study, it was observed that HEAs have good tribological properties which permit their prospective usage in the production of strength-demanding, wear-demanding, and temperature-demanding components. The addition of BCC-forming and FCC-forming elements would help in improving the wear properties of HEAs. It was also observed from the literature that the incorporation of post-processing treatment, laser cladding, shot peening, or the coating of SPSed composites would increase the effective performance and durability of HEAs prepared with SPS.
