Microstructure, Corrosion Behaviour and Microhardness of Non-equiatomic Fe1.5CoNiCrCux (0.5 ≤ x ≤ 2.0) High-Entropy Alloys
The microstructure, electrochemical corrosion behaviour and microhardness of Fe 1.5 CoNiCrCu x ( x = 0.5, 1.0, 1.5 and 2.0) high-entropy alloys (HEAs) were investigated by X-ray diffraction (XRD), scanning electron microscopy and an electrochemical workstation. The XRD spectra of Fe 1.5 CoNiCrCu x...
