Microstructure, mechanical, and thermal properties of compositionally complex (Hf,Zr,Nb,Ti)B2‒LaB6 ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.
