Abstract

In this paper, a high-entropy alloy Fe₃₄Cr₃₀Mo₁₅Ni₁₅Nb₃Al₃ was prepared via vacuum induction melting technique. The cast alloy consists of FCC phase, Laves phase and B2-NiAl phase. Then, the high-entropy alloy was subjected to corrosion test at 500^oC in static molten Pb-Bi eutectic (MBE) containing 10^-6% oxygen (in mass fraction) for 1000, 1500 and 2000 h, respectively. The results showed that after corrosion test, the high entropy alloy did not show obvious signs of being attacked by molten Pb-Bi eutectic, namely, there was no obvious dissolution of alloy components and phase transformation, and no obvious inward permeation of Pb and Bi from MBE into the alloy. Only a continuous Fe-Cr spinel scale was formed on the Laves phase region after static corrosion from 1000 h to 2000 h. It is worth mentioning in particular that after exposure for 1000 h, both of Fe-Cr spinel and Cr-depleted Fe-Cr spinel was formed on the surface of FCC/B2-NiAl phase region. As the corrosion time increased to 1500 h, the outer scale of Cr-depleted Fe-Cr spinel formed on the FCC/B2-NiAl phase region spalled off. After exposure for 2000 h, Fe₃O₄ was generated above the Fe-Cr spinel scale, and covered the entire surface of FCC/B2-NiAl phase region. In conclusion, the oxide scales formed on the high-entropy alloy are very thin and compact, with a maximum thickness less than 3 µm, so that the high-entropy alloy presented good resistance to MBE corrosion. The outstanding corrosion resistance of high-entropy alloy may be attributed to the homogeneous distribution of Laves phase, which effectively suppresses the outward diffusion of components of the high-entropy alloy.
