“…8(b) during initial $5 ks of exposure to air the oxide film grows nearly linearly at 7 pm/s, while later the growth rate of film decreases quickly with time by 3 orders in magnitude and the process becomes nonlinear. Linear kinetics indicates that initially the growth process is controlled by surface diffusion and adsorption of oxygen [50] and the oxidation process changes drastically after about 5 ks. This film is rather thick for pure metals and crystalline alloys [24,25], and influences the corrosion resistance of CuAZrAAl BMG [51].…”

“…During preoxidation, the pO 2 is about 10 –2 atm in the convection section. Cr 2 O 3 , Fe 2 O 3 , and NiO are thermodynamically stable at 700 °C . During presulfidation, the pO 2 and pS 2 varies along the length of the convection section.…”

The influence of presulfidation and H2S cofeeding on the carbon formation on SS304 alloy in the ethane–steam cracker was investigated in a laboratory-scale quartz reactor setup. SS304H coupons and SS304L powder samples were exposed to ethane–steam and dry ethane in varying H2S content (0–50 ppm), and the SS304 samples were characterized by scanning electron microscopy. This study shows that H2S cofeeding decreases catalytic carbon formation; while it increases the pyrolytic carbon formation during ethane–steam cracking. Preoxidation, presulfidation, and addition of steam to ethane feed also reduces the amount of catalytic carbon formed on the SS304H surface in short-term experiments (4 h). Presulfidation and addition of H2S to ethane feed significantly influences the shape and size of the carbon formed on the surfaces of investigated metal alloys. Presulfidation and H2S cofeeding reduced spalling of the SS304H coupon surface during coking/decoking and thermal cycling.

“…One exception is a paper by Chen et al [ 13 ], where only some aspects of high-temperature oxidation of refractory HEAs are considered (moreover, a sufficient amount of new data has been published over the past three years). The Ellingham diagram [ 14 , 15 ], which shows the change in the Gibbs energy of the formation of metal oxides depending on the temperature and composition of the gas phase, can give some idea of the possible oxidative behavior of HEAs at high temperatures.…”

“…On the other hand, the possibility of high-temperature oxidation of platinum-group metals at pressures close to atmospheric is hardly worth studying. If we analyze the data of the Ellingham diagram [ 14 , 15 ], as well as the data of the Pilling-Bedworth ratio [ 16 ] (which is a criterion for the continuity of the formed oxide film), we can conclude that interesting data of oxidation can be observed in HEAs based on metals of the Fe subgroup and HEAs based on refractory transition metals. Therefore, in this review, we analyze works devoted to the high-temperature oxidation of these groups of HEAs.…”

High-Temperature Oxidation of High-Entropic Alloys: A Review

et al. 2021

View full text Add to dashboard Cite

Over the past few years, interest in high-entropic alloys (HEAs) has been growing. A large body of research has been undertaken to study aspects such as the microstructure features of HEAs of various compositions, the effect of the content of certain elements on the mechanical properties of HEAs, and, of course, special properties such as heat resistance, corrosion resistance, resistance to irradiation with high-energy particles, magnetic properties, etc. However, few works have presented results accumulated over several years, which can complicate the choice of directions for further research. This review article presents the results of studies of the mechanisms of high-temperature oxidation of HEAs of systems: Al-Co-Cr-Fe-Ni, Mn-Co-Cr-Fe-Ni, refractory HEAs. An analysis made it possible to systematize the features of high-temperature oxidation of HEAs and propose new directions for the development of heat-resistant HEAs. The presented information may be useful for assessing the possibility of the practical application of HEAs in the aerospace industry, in nuclear and chemical engineering, and in new areas of energy.
