Short-Range Order and Origin of the Low Thermal Conductivity in Compositionally Complex Rare-Earth Niobates and Tantalates
Andrew J. Wright, Qingyang Wang, Yi-Ting Yeh +5
Rare-earth niobates and tantalates possess low thermal conductivities, which can be further reduced in high-entropy compositions. Here, a large number of 40 compositions are synthe…
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…
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…
Part I: Theoretical Predictions of Preferential Oxidation in Refractory High Entropy Materials
Lavina Backman, Joshua Gild, Jian Luo +1
High entropy materials, which include high entropy alloys, carbides, and borides, are a topic of substantial research interest due to the possibility of a large number of new mater…
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 (…
