High‐Entropy Ti, Zr, Hf, Ta Multiphase Diboride with Deformation Resistance up to 2000 °C

Advanced Engineering Materials, Volume 27, Issue 10, May 2025.
Ceramics are brittle and strength decreases with temperature. The multiphase high‐entropy (Ti0.25Ta0.25Hf0.25Zr0.25)B2 with heterogeneity at the nano‐ and microscale demonstrates deformation resistance up to 2000 °C, with maximum bending strength at 1800 °C.

When Two Becomes Three: Predicting Stable Ternary Boron‐Based Compounds by Populating Unique Lattice Sites in Binary Prototype Structures

Advanced Theory and Simulations, Volume 8, Issue 5, May 2025.
By substituting lattice sites in 16 binary prototypes, over 27 000 boron‐based ternary compounds are studied, revealing 155 stable candidates. The analysis identifies 31 compounds with superior hardness and elastic moduli compared to their binary counterparts.
