Research Abstract
Many high-entropy alloys are known to exhibit peculiar mechanical properties which conventional alloys cannot achieve. In the planned research, atomic structure, atomic diffusion and dislocations that carry plastic flow in high-entropy alloys were investigated down to an atomistic level by effective combinations of some advanced characterization methods such as nano-mechanical testing, scanning transmission electron microscopy, synchrotron X-ray diffraction and three-dimensional atom-probe, and factors controlling the peculiar mechanical properties based on the high-entropy effects of high-entropy alloys, high-entropy glasses and high-entropy ceramics were elucidated in order to reveal the essence of these high-entropy materials.
