High temperature creep of 20 vol.% SiC-HfB2 UHTCs up to 2000 °C [PDF]

open access: yes, 2017
High temperature compressive creep of SiC-HfB2 UHTCs up to 2000 °C has been studied. Microstructural analysis after deformation reveals formation of new phases in the Hf-B-Si and Hf-B-Si-C systems, which are responsible for the poor creep resistance.

Ablation Properties of HfC–SiC–WC Ultra‐High Temperature Ceramics Produced by Pressureless Sintering

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
Schematic diagram highlighting the processes that occur during ablation testing of HfC–SiC and HfC–SiC–WC. ABSTRACT HfC–SiC is one of the leading thermal insulation ceramics that has the potential to perform well under high thermomechanical loads. In this study, we explore the use of pressureless sintering to produce this material at relatively low ...
