High Entropy Alloys (HEAs) are loosely defined as solid solution alloys that contain more than five principal elements in equal or near equal atomic percentage. The concept of high entropy introduces a new path of developing advanced materials with unique properties, which cannot be achieved by the conventional micro-alloying approach based on only one dominant element. In contrast, HEAs have a number of constituent elements in nearly equal portions and the increased disorder consequently stabilizes a single phase solid solution. Neutron diffraction is the first choice for getting detailed structural information on HEA samples. However, due to the high number of contributing elements, it is difficult to derive adequate structural data from a single diffraction experiment. Due to the above difficulties, neutron Compton scattering is the local dynamics probe of choice.
