“…The nitrides and carbides from HEAs significantly improve the characteristics of materials: radiation, wear, and corrosion resistance. Many different HEAs have been fabricated and investigated; however, the coatings based on such alloys do not always possess excellent physicalmechanical properties [6][7][8][9]. Fabrication of nitride coatings from high-entropy alloys with high hardness, oxidation resistance, and thermal stability is an issue of current interest.…”

a b s t r a c tThe multicomponent nitride coatings from TiZrNbAlYCr high entropy alloy (HEA) were fabricated using the vacuum-arc method. The effect of nitrogen pressure on the crystallite size, elemental and phase composition of (TiZrNbAlYCr)N coatings was investigated. A bias voltage applied to the substrate during the deposition process was À200 V. The partial nitrogen pressure was 0.05 Pa, 0.27 Pa, and 0.5 Pa. Bodycentered cubic (BCC) lattice with crystallites of 15 nm in size was formed at the lowest pressure. An increase in the pressure led to the formation of the two-phase structure: BCC phase with crystallite size of 15 nm and face-centered cubic (FCC) phase with crystallite size of about 3.5 nm. The same two-phase state was found in coatings fabricated at 0.5 Pa, while the mean crystallite size was 7 nm. The maximum hardness of the deposited coatings was about 47 GPa.

“…The complexity in the atomic structure of HEAs as accompanied by heavy solid solution strengthening, binding enhancement and fine-grain strengthening, can lead to superior mechanical properties at high temperatures, such as relatively high hardness (Huang et al, 2007;Lin et al, 2011)and mechanical strengths (Zhou et al, 2007a;Yang et al, 2012), good thermal stability (Sriharitha et al, 2014)and work hardenability (Varalakshmi et al, 2008), excellent anticorrosive properties (Chou et al, 2010a, b)and wear resistance (Wang et al, 2013(Wang et al, , 2011, and unique magnetic properties (Tariq et al, 2013;Liu et al, 2012). Such a combination of impressive mechanical properties renders HEAs one of the most promising candidate structural materials for future engineering, and industrial applications, such as sport goods, nuclear technology, aerospace engineering, superconductorand hydrogen storage (2014; Otto et al, 2013a;Zhang et al, 2013;Tsai et al, 2013a;Sheng et al, 2013;Tsai et al, 2013b;Ng et al, 2012;Zhuang et al, 2012;Shun et al, 2012b;Hemphill et al, 2012;Zhang et al, 2012a;Senkov & Woodward, 2011a;Hsu et al, 2011).…”

Over the past decades, high entropy alloys (HEAs) have attracted continuously increasing research efforts because of their technological promise for structural applications and their scientific interest as a multi-component alloy exhibiting an overall random solid solution structure with high mixing entropy at high temperature. In this summary, we briefly review the recent studies focused on the structure and mechanical behavior of HEAs, covering the important issues from phase stability to elastic modulus, mechanical strength, hardness and fatigue resistance. Finally, we highlight a few key findings recently reported for HEAs and discuss the outstanding issues yet to be resolved.

“…Получение нитридов и карбидов из ВЭС позволяет существенно улучшить такие характеристики материалов, как радиационная стойкость, сопротивление износу, коррозии и др. В настоящее время получено и исследовано большое количество различных многоэлементных сплавов, в том числе с высокой энтропией смешения [7][8][9][10], но при этом нитридные покрытия на их основе далеко не всегда обладают необходимыми физико-механическими свойствами. Поэтому задача создания нитридных покрытий из многоэлементных сплавов, обладающих высокой твердостью, сопротивлением износу и повышенной коррозионной стойкостью, до сих пор актуальна.…”

Multicomponent nanostructured coatings based on (TiZrNbAlYCr)N with a hardness as high as 47 GPa were obtained by cathodic arc deposition. The effect of partial nitrogen pressure P _N (with constant bias potential U _ b =–200 V applied to the substrate) on the phase-composition variation, the size of crystallites, and their relation to the microstructure and hardness was investigated. An increase in the nitrogen pressure resulted in the formation of two phases with characteristic BCC (the lattice period is 0.342 nm) and FCC lattices with averaged nanocrystallite sizes of 15 and 2 nm. At a high pressure of 0.5 Pa, crystallites in the FCC phase with a lattice period of 0.437 nm grew in size to ~7 nm. The hardness of deposited coatings with larger (3.5 nm) FCC-phase crystallites and smaller (7 nm) BCC-phase crystallites was enhanced considerably.
