High density NbB2-NbC composites: From Controllable synthesis of NbB2-NbC composite powers to strengthening and toughening by adding SiC J. Alloys Compd. (IF 5.8) Pub Date : 2025-02-06 Huan Liu, Wenzhou Sun, Youjun Lu, Shuai Wei
In this study, NbB2-NbC nanocomposite powders were synthesized using the boron/carbon thermal reduction method, followed by the fabrication of NbB2-NbC-based composite ceramics via the SPS technique. Initially, the fundamental reaction process was elucidated, and a phase diagram was constructed through thermodynamic calculations to guide process and formulation optimizations. By increasing the synthesis
