| Abstract Scope |
The first part of this presentation focuses on using versatile nanomechanical tools for HEA studies, including nanoindentation, microcompression, high-temperature deformation, fracture measurement, and in situ electron microscopy. With these approaches, many interesting phenomena and properties of HEAs have been unveiled, for example, size-dependent strength, and fracture, which are difficult or impossible, to be measured in macroscopic experiments. The second part of this presentation will focus on the development of refractory nanocrystalline (nc) HEAs, which are harder and more thermally stable than conventional nc-alloys, using various methods. |
