High-temperature stable refractory high-entropy nanoalloys with enhanced sinterability
Mingde Qin, Sashank Shivakumar, Jian Luo
Nanocrystalline alloys (nanoalloys) are prone to grain growth. It is known that grain boundary segregation and precipitation can stabilize nanoalloys, but the stabilization becomes…
21-Component Compositionally Complex Ceramics: Discovery of Ultrahigh-Entropy Weberite and Fergusonite Phases and a Pyrochlore-Weberite Transition
Mingde Qin, Heidy Vega, Dawei Zhang +4
Two new high-entropy ceramics (HECs) in the weberite and fergusonite structures, along with unexpected formation of ordered pyrochlore phases with ultrahigh-entropy compositions an…
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…
Accelerating Materials Discovery with Bayesian Optimization and Graph Deep Learning
Yunxing Zuo, Mingde Qin, Chi Chen +4
Machine learning (ML) models utilizing structure-based features provide an efficient means for accurate property predictions across diverse chemical spaces. However, obtaining equi…
Bulk High-Entropy Hexaborides
Mingde Qin, Qizhang Yan, Yi Liu +7
For the first time, a group of CaB6-typed cubic rare earth high-entropy hexaborides have been successfully fabricated into dense bulk pellets (>98.5% in relative densities). The sp…
High-Entropy Rare Earth Tetraborides
Mingde Qin, Qizhang Yan, Haoren Wang +2
Six high-entropy rare earth tetraborides of the tetragonal UB4-prototyped structure have been successfully synthesized for the first time. The specimens are prepared from elemental…
High-Entropy Monoborides: Towards Superhard Materials
Mingde Qin, Qizhang Yan, Haoren Wang +2
Single-phase high-entropy monoborides (HEMBs) of the CrB prototype structure have been synthesized for the first time. Reactive spark plasma sintering of ball milled mixtures of el…
Dual-Phase High-Entropy Ultra-High Temperature Ceramics
Mingde Qin, Joshua Gild, Chongze Hu +7
A series of dual-phase high-entropy ultrahigh temperature ceramics (DPHE-UHTCs) are fabricated starting from N binary borides and (5-N) binary carbides powders. >~99% relative dens…
Dissolving and Stabilizing Soft WB2 and MoB2 Phases into High-Entropy Borides via Boron-Metals Reactive Sintering to Attain Higher Hardness
Mingde Qin, Joshua Gild, Haoren Wang +3
Five single-phase WB2- and MoB2-containing high-entropy borides (HEBs) have been made via reactive spark plasma sintering of elemental boron and metals. A large reactive driving fo…
Single-Phase High-Entropy Intermetallic Compounds (HEICs): Bridging High-Entropy Alloys and Ceramics
Naixie Zhou, Sicong Jiang, Timothy Huang +3
High-entropy intermetallic compounds (HEICs) were fabricated by mechanical alloying and spark plasma sintering to fill a knowledge gap between the traditional high-entropy alloys (…
