Effect of Sc/Y Co-Doping on Microstructure and High-Temperature Oxidation Properties of FeCoNiCrAl High-Entropy Alloys
Published 2025-06-01“…To improve the oxidation resistance of FeCoNiCrAl high-entropy alloy in high-temperature environments, Sc/Y was co-doped in FeCoNiCrAl alloy.The high-entropy alloys FeCoNiCrAl and FeCoNiCrAlScY were prepared by vacuum induction melting method, and the microstructure morphology of the alloys was analyzed by optical microscope,scanning electron microscope and transmission electron microscope.Meanwhile, the phase composition of the high-entropy alloy was tested by X-ray diffractometer, and the influence of doping Sc and Y elements on the high-temperature oxidation performance of the alloy was studied by high-temperature tube furnace.Results showed that both FeCoNiCrAl and FeCoNiCrAlScY high-entropy alloys were composed of two nanoscale phases, namely the A2 phase enriched with Fe and Cr elements, and the B2 phase enriched with Ni and Al elements.The FeCoNiCrAl alloy had a body-centered cubic structure (BCC).When Sc and Y elements were added, a face-centered cubic structure (FCC) enriched with Sc and Y elements appeared,and the hardness of the alloy increased significantly at the same time.After short-term oxidation at 1 200 ℃, both the FeCoNiCrAl and FeCoNiCrAlScY alloys developed oxide scales composed exclusively of α-Al2O3, while their substrate matrices underwent a phase transformation from BCC to FCC structure.The FeCoNiCrAl alloy exhibited oxide scale spallation after only 5 min of high-temperature oxidation, whereas the FeCoNiCrAlScY alloy demonstrated oxide scale spallation after 30 min of high-temperature oxidation.…”
