What is it about?
High entropy alloys exhibit a unique basis of strength due to fluctuations in shear-fault energy on the slip plane, which cause travelling dislocations to fluctuate in shape and energy. The energy fluctuations give rise to a unique form of strength not present in traditional dilute alloys.
