Abstract
Multicomponent alloys, particularly high-entropyentropy alloys (HEAs), have revolutionized materials science by introducing novel alloying strategies based on configurational entropy. Unlike conventional alloys (CAs), HEAs consist of five or more principal elements in near-equimolar proportions, stabilizing single-phase solid solutions and exhibiting superior mechanical, thermal, and corrosion-resistant properties. This chapter provides a comprehensive exploration of the history, classification, design strategies, phase stability, manufacturing techniques, and applications of multicomponent alloysmulticomponent alloys. Key developments in computational modeling, including CALPHADCALPHAD and machine learning-assisted alloy design, are also discussed. The growing potential of HEAs in aerospace, energy, biomedical, and structural applications underscores their significance in next-generation materials development.
