Abstract

The corrosion and passive behavior of AlNbTiZrSi_x high-entropy alloys (HEAs) with different Si contents were investigated in simulated seawater environment at room temperature. The results showed that the average grain size decreased with an increase in Si content, which was associated with the inhibiting effect on grain growth due to the precipitation of Zr₅Al₃ phase. The passive film of the HEAs primarily consisted of TiO₂, Nb₂O₅, and ZrO₂. Preferential corrosion occurred in Zr₅Al₃ phase regions, and the addition of Si reduced passive film stability, worsening corrosion resistance.
