High-Entropy Grain Boundaries
Jian Luo, Naixie Zhou
Do high-entropy alloys and ceramics have their grain boundary (GB) counterparts? As the concept of high-entropy grain boundaries (HEGBs) was initially proposed in 2016, this articl…
Computing Grain Boundary 'Phase' Diagrams
Jian Luo
Grain boundaries (GBs) can be treated as two-dimensional (2-D) interfacial phases (also called 'complexions') that can undergo interfacial phase-like transitions. As bulk phase dia…
Discovery of a reversible redox-induced order-disorder transition in a 10-cation compositionally complex ceramic
Dawei Zhang, Yan Chen, Tianshi Feng +4
This study discovers a reversible order-disorder transition (ODT) in a 10-cation compositionally complex ceramic, (Nd0.15Pr0.15Dy0.8Ho0.8Er0.8Ti0.2Yb0.1Hf0.1Zr0.1Nb0.8)O7-delta, in…
A New Type of Compositionally Complex M5Si3 Silicides: Cation Ordering and Unexpected Phase Stability
Sashank Shivakumar, Mingde Qin, Dawei Zhang +3
A new type of compositionally complex (medium- or high-entropy) M5Si3 silicides is synthesized. Both (V1/5Cr1/5Nb1/5Ta1/5W1/5)5Si3 and (Ti1/5Zr1/5Nb1/5Mo1/5Hf1/5)5Si3 form single-p…
