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 exhibit high oxidation resistance. To determine candidate MPEAs, we simulated CALPHAD data of 2000 randomly selected, 5- and 4- element, non-equimolar compositions in our chosen 14-element palette space. Because oxidation behavior is difficult to predict for MPEAs, we made use of a regression model fitted on experimental data found in literature. Candidate alloys were screened, arc-melted, characterized, and tested for oxidation. 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.
