Effects of the element La on the corrosion properties of CrMnFeNi high entropy alloys

Molten salt synthesis of CrMnFeNi alloy nanopowder passivated by TiOx–ZrOy shell used as a superior catalyst support in liquid-phase hydrogenation

“…For TiZrCrMnFeNi(800), clearer peaks were observed around 30–50°. According to the previous works, 19,20 CrMnFeNi HEA has a face-centered cubic (FCC) structure, which corresponds to the crystal structure of nickel metal. After careful examination of the peak assignment results (Fig.…”

“…In this study, we prepared a CrMnFeNi alloy nanopowder passivated by a TiO x -ZrO y surface shell, expressed as TiO x -ZrO y / CrMnFeNi, using a molten salt synthesis method. An equimolar CrMnFeNi solid solution alloy is known as one kind of highentropy alloy (HEAs), [19][20][21] piquing the interest of researchers these days because of their superior physical/chemical properties. [22][23][24][25] Since the work functions of Cr (4.5 eV), Mn (4.1 eV), and Fe (4.7 eV) are lower than Ni (5.2 eV), the CrMnFeNi alloy can have a lower work function than Ni.…”

A review on Corrosion of High Entropy Alloys: Exploring the Interplay Between Corrosion Properties, Alloy Composition, Passive Film Stability and Materials Selection

“…Manganese is often reported as a deleterious element with respect to the passive film stability of HEAs 46,47 . In fact, the candidates with the worst corrosion resistance in Figure 1 are 60 -a and 60 -b, as indicated by the red balloon. As shown in Table 1, Mn is a common alloying element for these alloys.…”

A Comparative Study on Corrosion Behaviors of Fe35Mn10Cr20Ni35 High‐Entropy Alloy and 304 Stainless Steel in Sulfuric Acid Aqueous Solution

“…These binding energy data are obtained from ref. [50]. For both alloys, by comparing the relative intensities of Fe ox and Fe hy , it can be considered that Fe ox species are the main iron oxide species in the passive film.…”
