Design of Ultra-High Temperature Ceramics for Improved Performance 28-Feb-2009 49 pages
Authors:  William G Fahrenholtz; Greg E Hilmas; Jeremy Watts; MISSOURI UNIV OF SCIENCE AND TECHNOLOGY ROLLA
The full text of this report is available for sale.The thermal shock behavior and thermal residual stresses were investigated for zirconium diboride-based ultra-high temperature ceramics. The research employed a combined experimental and finite element modeling approach to understand the factors that affected the magnitude and spatial extent of residual stresses. Then, engineered architectures were designed and fabricated to mitigate thermal stresses. This approach led to an improvement in thermal shock behavior. Whereas the strength of conventional SiC particulate reinforced ...
