| Abstract Scope |
“Multi-principal-element compositions” was a breakthrough of alloy compositions. Professor Cantor and I had independently explored this field near the end of 20th century and published related papers. To emphasize the importance of high mixing entropy in enhancing the solid solution phases, high-entropy alloys having at least five principal elements, medium-entropy alloys having 3 or 4 principal elements and low-entropy alloys having 1 or 2 elements are defined. Besides the high-entropy effect, other three core effects: lattice distortion, sluggish diffusion and cocktail, can help the understanding of high-entropy alloys. Nowadays, many new materials have been presented to overcome the bottlenecks of traditional alloys in applications and even creating new applications. The related papers display an exponential growth in yearly numbers since 2004, and a broad and far-reaching influence. Recently , I have led a team to industrialize green and healthy high-entropy material technology in both domestic and foreign industries. |
