Synthesis of Dual Phase High Entropy Ultra‐High Temperature Ceramics From Different Carbon Sources

International Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT Dual phase (Hf,Nb,Ta,Ti,Zr)C‐(Hf,Nb,Ta,Ti,Zr)B2 ceramics were synthesized by boro‐carbothermal reduction of oxides with different carbon black powders. The starting materials reacted differently based on the particle size, surface area, and additives in the carbon powder.

Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction

Advanced Science, Volume 13, Issue 50, 7 September 2026.
An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...

Enhanced Mechanical Properties Via Boron‐Induced Multi‐Mechanism Strengthening in (NbTaTi1.5V)100‐xBx Refractory High Entropy Alloys

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A trace amount of boron is introduced into NbTaTi1.5V RHEA, forming a finegrained BCC+TiO+TiB microstructure. The TiB phase generates numerous dislocations, strengthening the alloy. The alloy exhibits 3610 MPa compressive fracture strength and 1060 HV microhardness, while retaining 14.8% fracture strain.
