TL;DR: Initial property assessments show that both the hardness and the oxidation resistance of these high-entropy metal diborides are generally higher/better than the average performances of five individual metal dibiaides made by identical fabrication processing.

TL;DR: In this paper, a new class of high-entropy perovskite oxides (i.e., multiple-cation solid solutions with high configurational entropies) has been synthesized.

TL;DR: In bismuth-doped polycrystalline nickel, it is found that ordered, segregation-induced grain boundary superstructures occur at randomly selected general grain boundaries, and that these reconstructions are driven by the orientation of the terminating grain surfaces rather than by lattice matching between grains.

TL;DR: In this paper, multicomponent alloying can be utilized to enhance the thermal stability of nanocrystalline alloys, and the grain boundary energy can be reduced significantly via both bulk and grain-boundary high-entropy effects with increasing temperature at/within the solid solubility limit, thereby reducing the thermodynamic driving force for grain growth.

TL;DR: In this article, several GB adsorption (segregation) and prewetting/premelting type complexion models in multicomponent alloys, in which the interactions among multiple adsorbates not only provide a route to control GB properties but also produce novel phenomena.
