“…Crystallographically, the typical atomic structure in HEAs includeface centered cubic (FCC) and/or body centered cubic (BCC) crystal structure(s), with or without nano-precipitates (Yeh et al, 2004a;Tong et al, 2005). 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.

“…Although in most of the recent studies the microstructure and mechanical properties of HEAs composed of elements that form substitutional solid solutions have been discussed, only few investigations report the designing of HEAs alloyed with interstitial elements, such as C, N, and B (Shun and Du, 2009;Wang et al, 2011;Wang et al, 2013;Zhang et al, 2013;Fang et al, 2014;Meng and Baker, 2015). One of the most promising singlephase fcc equiatomic CoCrFeMnNi HEA possessing a relatively low yield strength (YS) but very high tensile elongations and exceptional fracture toughness even at cryogenic temperatures (Cantor et al, 2004;Otto et al, 2013;Gludovatz et al, 2014;Stepanov et al, 2015;Xiang et al, 2020) showed a pronounced increase in YS, ultimate tensile strength (UTS), and high uniform elongations to fracture with the dissolution of 0.5 at% C (Wu et al, 2015).…”

The effect of heat treatment on the mechanical properties of two high-carbon-containing (1.5 and 3 at%) single-phase face-centered cubic (fcc) Fe40.4Ni11.3Mn34.8Al7.5Cr6 high-entropy alloys is reported in this study. In the cold-rolled (CR) condition, the 1.5 and 3 at% C-containing alloys, referred to as CR1 and CR2, respectively, demonstrated yield strength values of 1,423 and 1,197 MPa, respectively. The corresponding values of elongation to failure was noted to be 4.05 and 4.46%, respectively. Upon heat treatment at 1,050°C, the CR1 and CR2 samples, referred to as HT1 and HT2 in the heat-treated (HT) condition, demonstrated yield strength values of 358 and 327 MPa, respectively. The elongation to failure of HT1 and HT2 was found to be 37.2 and 26.4%, respectively. The change in mechanical properties brought about by heat treatment was understood by studying the phase composition, microstructure, and crystallographic texture of the material in the CR and HT conditions. Despite the high-temperature heat treatment, the Fe40.4Ni11.3Mn34.8Al7.5Cr6 alloy retained a single-phase structure, indicating good phase stability. However, heat treatment caused a change in the grain structure. The CR materials exhibited an elongated grain structure, whereas the HT materials had an equiaxed microstructure. The CR and HT samples were found to exhibit a weak crystallographic texture although heat treatment had caused the {111} poles to orient themselves parallel to the rolling plane, whereas the CR material had a distribution of {200} poles at 45° to the rolling plane.

“…Surface modification technologies are essential to fabricate materials that can withstand hostile environments and severe operating conditions encountered in various modern manufacturing industries. Over the past few decades, two main approaches have been employed to improve the metal surface; one is microstructural modification by adding alloying elements with the dispersion of hard phase and different heat treatment procedures, and another is surface engineering, such as the application of hard coatings, films, and surface treatments. − Nevertheless, most traditional and recently industrialized technologies are unreasonable to use due to limitations such as inefficient diffusion kinetics, processing complications, or difficult experimental setup. − To enhance the service life of the steel surface, a low-alloyed steel substrate with a high-alloyed coating is the most effective solution . Common methods for applying such coatings are composite casting, deposit welding, hot isostatic pressing (HIP) cladding, , etc.…”

In this study, we have demonstrated an innovative single-step, low-cost approach for producing a hybrid layered steel surface with superior properties using waste as the resource. This promising method of transforming an industrial grade steel surface into a multilayered multiphase ceramic/diffused subsurface structure using only the waste source could replace technically challenging and expensive high-performance materials. Strong chemical bonds can be achieved between metal and ceramic structures if a suitable structure can be generated by the judicious choice of materials and processes. We recovered various ceramic materials (Ti, Al, Si/nitrides, oxides, etc.) from a complex mixture of wastes, such as automated shredder residue and metalized plastics from food packaging, through a controlled selective reaction to generate a chemically bonded multiphase ceramic and diffused subsurface on high-carbon steel surface as an ultrahard ceramic surface. The diffused subsurface contains submicrometer-sized carbides (Cr/Mn/SiC) which formed by diffusion of carbon into the base metal. Our result reveals that by turning the normal high-carbon steel surface into a multiphase ceramic/diffused subsurface structure, a seamless gradient of hardness from 14.5 GPa in the nanoceramic layer to 6.5 GPa in the base material can be achieved.
