Title: A Quick Screening Approach for Design of Multi-Principle Element Alloy with Solid Solution Phase

Abstract

Multi-principle element alloys (MPEAs) provide an innovative way to design materials with potential applications in extreme conditions, such as high-dose irradiation in nuclear reactors, high temperatures in aeronautic and aerospace engineering, etc. However, the composition design and optimization of MPEAs are challenging due to the vast options and complexity which make traditional theory and methods insufficient or even invalid. To effectively design MPEAs, a two-parameter approach is developed based on newly proposed enthalpy and entropy-enthalpy competition parameters. This approach can not only be used to classify conventional steels, high-entropy steels (HESs), high-entropy alloys (HEAs) and amorphous alloys, but also to predict the optimal composition of MPEAs with stable solid solution (SS) phases. The optimal compositions of three sets of Fe-Mn-Cr-Co-Ni alloys are quickly screened from millions of options to form HESs or HEAs with stable SS phases. This quick screening approach can also be applied to design other alloys and facilitate the research and development of MPEAs possessing the targeted properties and economic acceptability.
