  Whilst multi-principal element alloys (MPEAs) remain a promising class of
materials owing to several attractive mechanical properties, their corrosion
performance is also unique. In this concise review, we present an emerging
overview of some of the general features related to MPEA corrosion, following a
decade of work in the field. This includes highlighting some of the key aspects
related to the electrochemical phenomena in MPEA corrosion, and the relevant
future works required for a holistic mechanistic understanding. In addition, a
comprehensive database of the reported corrosion performance of MPEAs is
presented, based on works reported to date. The database is assembled to also
allow users to undertake machine learning or their own data analysis, with a
parsed representation of alloy composition, test electrolyte, and corrosion
related parameters.
