The Marian group has been awarded a three-year NSF proposal to study the deformation mechanisms of refractory high-entropy alloys. These materials are multicomponent systems containing four or more transition metal elements in approximately equal proportions and –since their inception– are showing tremendous potential for thermomechanical applications. However, due to their complex chemistry, understanding the mechanisms under which they deform is a challenge of combinatorial nature. Our researchers will (i) develop computational models to replicate how these alloys form and how they deform, and (ii) employ latest-generation experimental devices with atomic-level precision to gain insight into their microscopic thermo-mechanical behavior in finely-controlled loading conditions. We expect that this project can create a fundamental framework to classify how these materials are studied and remove some of the uncertainties associated with their composition and mechanical behavior.
