Abstract Scope Multi-Principle Element Alloys (MPEAs) are shown to have exceptional properties and demonstrate promise as a new methodology for alloy discovery. We focus on screening alloys that can be deposited as coatings by additive manufacturing and will further exhibit high oxidation resistance. To determine candidate MPEAs, we simulated CALPHAD data of 5 and 4 element equimolar combinations from a 12-element palette to screen alloys that were single phase at the solidus. Because oxidation behavior is difficult to predict for MPEAs, we made use of a regression model fitted on experimental data found in literature. We then arc-melted, characterized, and further screened candidate alloys based on oxidation behavior. To determine their compatibility with additive manufacturing, cracking susceptibility was tested with single laser track experiments. Given the complex interplay between oxidation resistance, MPEAs, and additive manufacturing, we expect our balanced modeling, machine learning, and experimental approach will lend insight in future MPEA development.
