“…This could be a reason for both lower breakdown potential of HEA investigated in this study compared with high interstitial austenitic stainless steels and decreased resistance of CrMnFeCoNi-C and CrMn-FeCoNi-CN compared to CrMnFeCoNi. This is confirmed by the findings of Lu et al [32] and Menghani et al [33].…”

“…The passive layer of HEA seems to be not as stable as that of high interstitial austenitic stainless steels, and thus more susceptible to pitting corrosion in chloridecontaining solutions, which could limit the application of HEA in marine environments. Susceptibility to localized corrosion is even increased by the presence of a second phase, as stated by Lu et al [32] and confirmed by Menghani et al [33], which was attributed to the impact of the second phase, e.g. carbides, on the formation of passive films.…”

“…This is consistent with the findings in the present study. Aluminum-alloyed HEA variants could have more promising applications in this field, as indicated in recent investigations [33,35]. However, the addition of Al could strongly affect the stability of the FCC structure towards a BCC structure, depending on its content.…”

The use of interstitial elements has been a key factor for the development of different kinds of steels. However, this aspect has been little explored in the field of high entropy alloys (HEAs). In this investigation, the effect of carbon and nitrogen in a near-equiatomic CrMnFeCoNi HEA is studied, analyzing their impact on the microstructure, and mechanical properties from 77K to 673K, as well as wear, and corrosion resistance. Carbon and nitrogen are part of the FCC solid solution and contribute to the formation of precipitates. An increase in the yield and ultimate tensile strength accompanied with a decrease in the ductility are the main effects of C and N. The impact toughness of the interstitial-free material is higher than that of C and C+N alloyed systems. Compared to CrNi and CrMn austenitic steels, the wear resistance of the alloys at room temperature is rather low. The surface corrosion resistance of HEAs is comparable to austenitic steels; nevertheless HEAs are more susceptible to pitting in chloride containing solutions.

“…The corrosion process, which is a gradual degradation process of material by chemical or electrochemical reaction with their environment, transforms a refined metal into a more chemically stable form such as sulfide, hydroxide, or oxide [ 102 , 103 , 104 , 105 ]. The corrosion resistance sometimes is a vital performance index to reflect the mechanical properties of the deposition by LMD when the working condition is poor such as high temperature, high pressure, corrosive atmosphere and so on.…”

Owing to the unparalleled advantages in repairing of high value-add component with big size, fabricating of functionally graded material, and cladding to enhance the surface properties of parts, the laser material deposition (LMD) is widely used. Compared to the continuous wave (CW) laser, the controllability of the laser energy would be improved and the temperature history would be different under the condition of pulse wave (PW) laser through changing the pulse parameters, such as duty cycle and pulse frequency. In this paper, the research status of temperature field simulation, surface quality, microstructural features, including microstructures, microhardness, residual stress, and cracking, as well as corrosion behavior of metallic coating created by pulsed laser material deposition have been reviewed. Furthermore, the existing knowledge and technology gaps are identified while the future research directions are also discussed.

“…For lubrication, mostly dry conditions were used but some studies also used H 2 O 2 , deionized water and acid rain (pH = 2). Previously, Tsai and Yeh et al [351], Kasar et al [352], Senkov et al [67], Sharma et al [16], Zhang et al [37], Li et al [42], Menghani et al [353] and Ayyagari et al [354] discussed the wear behaviors of HEAs. In this review, we will analyze the tribological studies of HEAs in terms of HEAs content variation, particle reinforcement, media and nitriding/carburizing/sulfurizing, temperature effects and oxide formation.…”

Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added to the principal metal. However, a new alloying technique emerged in 2004 with the concept of adding several principal elements in or near equi-atomic concentrations. These are popularly known as high entropy alloys (HEAs) which can have a wide composition range. A vast area of this composition range is still unexplored. The HEAs research community is still trying to identify and characterize the behaviors of these alloys under different scenarios to develop high-performance materials with desired properties and make the next class of advanced materials. Over the years, understanding of the thermodynamics theories, phase stability and manufacturing methods of HEAs has improved. Moreover, HEAs have also shown retention of strength and relevant properties under extreme tribological conditions and radiation. Recent progresses in these fields are surveyed and discussed in this review with a focus on HEAs for use under extreme environments (i.e., wear and irradiation) and their fabrication using additive manufacturing.
