摘要：
The corrosion behaviours of two high entropy alloys (HEAs, namely Fe-Al-Ni-Cr-Co and Fe-AlNi-Cr-Co-Mn) in molten Al, each with and without pre-oxidation treatment, were investigated. Both bare alloys lost their thickness owing to dissolution, and various intermetallic compounds formed on their substrate surfaces during immersion in molten Al. Pre-oxidation treatment gave rise to the formation of an effective oxide barrier on each alloy surface against molten Al attack. The characteristics of pre-formed oxides in resisting molten Al attack were examined using electron backscatter diffraction (EBSD) analysis.
