In the past, metallic alloys were produced with one or two dominant metals, and it was widely believed that the more types of metals added, the more brittle the resulting alloy would be, making it unusable. High-Entropy Alloys materials were proposed and developed by Professor Jien-Wei Yeh in 1995. He believed that multiple elements would induce a high entropy effect which promotes their mixing to form solid solutions. High-Entropy Alloys can be lighter and stronger than conventional alloys, while being much more resistant to corrosion, radiation or severe wear. They can be applied in industries such as smart machinery, biomedicine, defense, and space technology. Through this exhibition, people have the opportunity to learn about the theory of High-Entropy Alloys and materials, the practical applications in various industries, as well as Professor Jien-Wei Yeh's philosophical thoughts, innovative spirit, and contributions in the field of materials.
