Thermal shock behavior of a variety of open-cell ceramic foams was evaluated using infrared heating and forced air cooling. The extent of damage after thermal shock was determined by a nondestructive, dynamic resonance technique. The damage in foams

A variety of open cell ceramic foams were subjected to rapid thermal cycles by infrared heating and forced air cooling to study the thermal fatigue behaviour of these materials. After cycling, the extent of damage in the samples was determined by mea

An experimental methodology is proposed to evaluate the thermal shock resistance of ceramics. A technique based on infrared heating has been developed to perform systematic and well controlled thermal shock experiments. This novel technique was used

Ceramic combustor liners require no film cooling on the hot-side and minimal backside cooling, due to their high temperature capability. The hotter combustor walls lead to minimal "wall quenching" and better carbon monoxide (CO) oxidation because les

Properties of piezoelectric ceramics important for actuator applications have been measured as a function of grain size. Fine grain piezoelectrics (≤1 μm) have been found to exhibit improved machinability and increased mechanical strength over con

The piezoelectric properties of relaxor based ferroelectric single crystals, such as Pb(Zn 1/3 Nb 2/3 )O 3 - PbTiO 3 (PZN-PT) and Pb(Mg 1/3 Nb 2/3 )O 3 - PbTiO 3 (PMN-PT) were investigated for electromechanical actuators. In contrast to polycrystalli
