“…Additionally, multi‐principle components in HEAs induce the so‐called cocktail effects . Due to these unique effects associated with the high entropy characteristic, HEAs exhibit high strength, good corrosion resistance, excellent thermal stability, high oxidation resistance, and good wear resistance …”

The AlCrFeNiMo0.5Tix (x = 0, 0.25, 0.4, 0.5) high entropy alloys were prepared by copper mold suction casting, and the structures and aqueous corrosion behavior of the alloys were investigated in the present study. It shows that all of these alloys possess BCC + B2 structures at various Ti contents, while Ti element is enriched in ordered B2 phase. With increasing Ti content, the passive film becomes more protective. The charge transfer resistance (Rct) value increases from 229 kΩ · cm2 for the AlCrFeNiMo0.5 alloy to 635 kΩ · cm2 for the AlCrFeNiMo0.5Ti0.5 alloy. Meanwhile, the pitting potential (Epit) increases from 90 mV for the AlCrFeNiMo0.5 alloy to 410 mV for the AlCrFeNiMo0.5Ti0.5 alloy. The present results indicate that the corrosion resistance of the AlCrFeNiMo0.5Tix high entropy alloys has been significantly enhanced by Ti additions.

“…It conveys the existence of two bcc phases associated with both DR and ID. Soare et al [24] reported a similar result, suggesting that one of the two bcc structures is ordered and the other is disordered. In addition, the peaks of bcc1 phase are quite similar to L2 1 superlattice structure of Heusler AlCu 2 Mn alloy; however, no superlattices peaks were observed [ 25,26].…”

“…The corrosion rate of the investigated alloy in 3.5% NaCl as a result of 672 h immersion test can be deducted by the following equation [24]: Where W is the total weight loss in gm, t is the exposure time in hrs, D stands for density in gm/cm 3 , and A is the exposed area in cm 2 . Table 6 provides the calculated corrosion rate after 672 h immersion in 3.5% NaCl.…”

Cu 45 Mn 25 Al 15 Fe 5 Cr 5 Ni 5 high entropy alloy was prepared using casting route. Detailed microstructural analysis revealed the formation of dendritic structure in the as-cast sample. The results showed that the dendrite (DR) regions are riched with Cu and Mn, while the inter-dendrite (ID) regions are riched with Cr and Fe. Metallographic investigation was conducted using optical microscope and scanning electron microscope as well. Determination of phase analysis was carried out using x-ray diffraction. Corrosion properties were studied via Auto LAB PGSTAT 302N, supplied with Nova software. The investigated alloy demonstrates superior corrosion resistance with average corrosion rate 0.056 mm year −1 .
