Structural stability of UHTCs in extreme environments

open access: yes, 2018
Hypersonic flights, re-entry vehicles, and propulsion applications all require new materials that can perform in oxidizing or corrosive atmospheres at temperatures in excess of 2000°C and sometimes over the course of a long working life.

Spark-plasma sintering of ZrB2 ultra-high-temperature ceramics at lower temperature via nanoscale crystal refinement

open access: yes, 2012
We have explored the feasibility of reducing the spark-plasma-sintering (SPS) temperature of additive-free ZrB2 ultra-high-temperature ceramics (UHTCs) via crystal size refinement of the starting powder down to the low nanoscale.
