Designing eutectic medium-entropy alloys CoFeNiTax with outstanding mechanical properties
Journal of Materials Research and Technology, 2023 The eutectic medium-entropy alloys CoFeNiTax (x = 0.4, 0.5, 0.6) were designed successfully based on binary eutectic systems and thermodynamics calculations in this study. With the increase of Ta content, the solidified microstructures evolved from hypoeutectic to full eutectic and finally to hypereutectic.

Multihyperuniform Long-Range Order in Medium-Entropy Alloys
, 2021 We provide strong numerical evidence for a hidden multihyperuniform long-range order (MHLRO) in SiGeSn medium-entropy alloys (MEAs), in which the normalized infinite-wavelength composition fluctuations for all three atomic species are completely suppressed as in a perfect crystalline state.
