Lattice Dynamics of High Entropy Alloy
High Entropy Alloys (HEAs), or single-phase random solid solutions, are characterized by excellent mechanical and magnetic properties, and have revolutionized the field of materials science. The core reasons for these remarkable behaviors are still unknown, however the local lattice strain caused by the use of 5 or more elements, and the chemical disorder present in such systems, makes HEAs an interesting candidate for studying the effect of local disorder and long-range order on the dynamics of the system. Until now, no investigation of the lattice dynamics of an HEA exists. Our group has already begun studying the transverse acoustic phonon dispersion of our single crystal HEA Fe20Cr20Co20Mn20Ni20, finding surprisingly long-living phonons. Here we propose to complete this study using IN5 to measure the longitudinal acoustic phonon dispersion. This proposal is part of the PhD thesis work of S. Turner.
