Thermal Shock Resistance of Ultra-High Temperature Ceramics
Thermal shock resistance of Ultra-High Temperature Ceramics is one of the most important parameters in UHTCs characterization since it determines their performance in many applications.In order to reflect practical cases,the temperature-dependent thermal shock resistance parameter of UHTCS was measured since the material parameters of UHTCs are very sensitive to the changes of temperature,The influence of some important thermal environment parameters and the size of the material on the thermal shock resistance and critical temperature difference of rupture of UHTCs at different stages in the thermal-shock process were investigated.The results show that thermal shock behaviour of the UHTCs is strongly affected by the size of the material and the thermal environments parameters,such as the surface heat transfer coefficient,heat transfer condition and initial temperature of the thermal shock.
