Advanced Characterization Techniques

High-Entropy Alloys

Abstract

This chapter first provides a brief introduction to some advanced microstructure characterization tools, such as three-dimensional (3D) atom probe tomography, high-resolution transmission electron microscopy, and neutron scattering. Applications of these techniques to characterize high-entropy alloys (HEAs) are illustrated in model alloys. Utilization of these advanced techniques can provide extremely useful structural and chemical information at the nanoscale. For example, the identification of nano-twins in the fracture-toughness crack region of an HEA may explain the anomalous increases in strength and ductility at cryogenic temperatures. Another striking feature of HEAs is the large local strain among neighboring atoms, which, in general, are arranged in a crystal structure with long-range order. Our understanding of these types of features, and their effect on material properties, will increase as the microstructural characterization techniques described here are further developed and applied to HEA research.
