High-Entropy Alloys

High-entropy alloys are usually defined as metallic materials with high entropy of mixing at their disordered state. They tend to form high-entropy disordered solid solutions and amorphous phases and get simpler microstructure. High-entropy alloys can include disordered solid solution alloys and high-entropy metallic glasses. In addition, highentropy ceramics based on the same "high entropy" concept can include carbides, nitrides, borides, and oxides. Recent advances in high-entropy alloys and ceramics have brought new conceptions to develop advanced materials, which may potentially overcome the challenges in increasing the property limits for the advanced energy and environment friendly materials.
