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.

Why is it important?

Understanding strength in high entropy alloys is important to pave ways for engineering the mechanical properties of these interesting alloys.


High entropy alloys are indeed interesting alloys to work on because a lot of the traditional concepts of physical metallurgy are not valid in these alloys.
