Paper Title:
Mechanical Properties Evaluation of Ultra-High Temperature Ceramics
  Abstract

Ultra-high temperature ceramics (UHTCs) have attracted increasing attention of material scientists and engineers due to their promising application in reactive atmospheres such as monatomic oxygen at high temperatures over 1600°C. However, the mechanical properties of this kind of ceramics at ultra-high temperature are difficult to measure because of the temperature limits of the furnace and fixture. In this work, an innovative measuring approach, trace analysis method, is presented for estimating the ultra-high temperature mechanical properties. Various material parameters, including elastic modulus, hardness, recovery deformation and energy dissipation capacity at ultra-high temperature could be determined via a residual indent trace that was induced by a fast impact of a ceramic conical indenter on the local area at high temperature.
