Notes:
Ultra-high temperature ceramics (UHTCs) have attracted increasing attention of materialscientists and engineers due to their promising application in reactive atmospheres such as monatomicoxygen at high temperatures over 1600°C. However, the mechanical properties of this kind of ceramics atultra-high temperature are difficult to measure because of the temperature limits of the furnace andfixture. In this work, an innovative measuring approach, trace analysis method, is presented for estimatingthe ultra-high temperature mechanical properties. Various material parameters, including elasticmodulus, hardness, recovery deformation and energy dissipation capacity at ultra-high temperature couldbe determined via a residual indent trace that was induced by a fast impact of a ceramic conical indenteron the local area at high temperature
