The effect of 7.5 at.% Al addition in Al7.5CoCrNi medium-entropy alloy (MEA) was investigated. The recrystallized Al7.5CoCrNi exhibited the microstructure of fine-grain face-centered cubic (FCC) phase altogether with the formation of NiAl-rich B2-pha

Solid solution interaction in medium- and high-entropy of Fex(CoCrMnNi)100-x (x = 20, 40, 50, and 60 at. %) alloys was evaluated theoretically. The different Fe contents were found to affect the yield strength (σy) of the Fex(CoCrMnNi)100-x system,

Solid solution strengthening effect was investigated in AlxCoCrNi medium-entropy alloy (MEA) with different Al content (x = 0–7 at.%). The result of X-ray diffraction indicates that the fully recrystallized phase was a single face-centered cubic (F

B2-precipitate formation in Al7.45(CoCrNi)92.55 (at.%) was investigated after two-stage annealing. Prior face-centered cubic (FCC) grain growth has been successfully controlled using the pinning effect of B2-precipitate. Electron backscattered diffra

The high-temperature oxidation behaviour of CoCrNi was investigated over different exposure times (6, 12, 24, and 48 h) at 900–1100 °C. The initial phase identification indicated that the tendency of oxide formation at 1100 °C was different after

The thermal oxidation behavior of Fex(CoCrMnNi)100-x high-entropy alloys (x = 20 and 40 at.%) and medium-entropy alloy (x = 60 at.%) at temperatures ranging from 900 °C to 1100 °C under air atmosphere was investigated. The oxidation kinetics of the

In order to produce structural products, Al-Zn-Mg alloys undergo various forming processes. Problems that are usually found in the forming process include peripheral coarse grain (PCG) and hot tearing which decrease mechanical properties and corrosio
