For the first time, a research group at the University of Maryland (UMD) has demonstrated the single phase nanoscale multi-principal element intermetallics (MPEIs) with up to eight metals—completely devoid of particle growth, or phase separation—via a novel multi-element disorder-to-order strategy. This approach demonstrates a general strategy for synthesizing MPEI nanoparticles, not only providing a step toward octonary intermetallics, but also enabling the synthesis of MPEIs at the nanoscale.

Nano-MPEIs are —roughly 4–5 nanometers diameter—composed of multi-elemental metals in definite proportions, as opposed to alloy, for example, which has variable proportions. The properties and formed by these intermetallic compounds are different from its constituents.

The study, led by Liangbing Hu, Herbert Rabin Distinguished Professor of Materials Science and Engineering (MSE) at the University of Maryland (UMD) and director of the Center for Materials Innovation (CMI)—was published in Science Advances on January 28, 2022. Mingjin Cui, a former MSE Faculty Assistant at UMD, served as the first author on the research paper.

"Precisely controlling the atomic ordering arrangement inside is a great challenge," said Hu. "We achieved the multi-elemental ordered intermetallic nanoparticles by unique disorder-to-order transition strategy. The strategy can be extended to produce a combinatorial library of intermetallic nanomaterials that may feature novel properties and applications."
