Jien-Wei Yeh
Jien-Wei Yeh is a pioneering materials scientist whose expertise spans aluminum and magnesium alloys, metal matrix composites, metallic glasses, coatings, reciprocating extrusion, and high-entropy materials (HEMs). Since 1995, he has led groundbreaking research that redefined alloy design by proposing material compositions beyond traditional boundaries, unlocking vast compositional possibilities across the Periodic Table. He coined and defined “high-entropy alloys (HEAs),” established their four core effects, and laid the theoretical foundation for this rapidly expanding field. His work further extended high-entropy concepts to ceramics, polymers, and composites, catalyzing global development of high-entropy materials. He has been elected as an academician in Academia Sinica, and has received many prestigious awards, including the Executive Yuan Award for Outstanding Science and Technology Contribution (2021) and the Taiwan Presidential Scientific Award (2025). In Stanford’s global rankings in scientific influence, he ranked second worldwide in Materials.
