Phonon dynamics in High Entropy Alloys
High Entropy Alloys (HEA), single-phase random solid solutions, characterized by excellent mechanical and magnetic properties, have revolutionized material science, and at the same time arisen new fundamental questions on alloy formation and the microscopic origin of such properties. At this day no investigation exists of the lattice dynamics of an HEA, which can be thought of as the prototype of chemical disorder. Here we propose to measure the density of states of the HEA Fe20Cr20Co20Mn20Ni20. Being intermediate between crystal and glass, presenting nanoscale elastic heterogeneities, like in a glass, but long range periodicity like in a crystal, the question whether there is a Boson Peak will be specifically addressed. This proposal is part of the PhD thesis work of S. Turner.
