| Abstract Scope |
Multi-principal element alloys (MPEAs) are garnering significant attention as promising materials for high-performance structural applications. While many efforts have been devoted to exploring the vast compositional spaces of MPEAs, high-throughput calculations are deemed to be an effective design approach. To this end in this study, we have developed a comprehensive first-principle structural database of MPEAs. The database includes information on phase stability and structural stability along with the mechanical properties. With this database, we have investigated the underlying mechanisms governing the mechanical properties of MPEAs using various data analysis techniques. Ductility-strength trade-offs in these systems are investigated across various phases. Our results provide fundamental insights into the mechanical behaviour of MPEAs and can guide the design and development of advanced structural materials for diverse applications. The approach presented in this study can also be extended to various complex materials including other high entropy systems to understand their mechanical behaviour. |
