RESEARCH DESCRIPTION
 | My research is primarily
focused on investigating the fundamental problems related to
processing, microstructure and behavior of high-temperature composites
for advanced aerospace structural and ground transportation
applications. |
- Deformation and Fracture
Behavior of High Temperature Composites
Our effort is to create
a science base in quantitative relations between the microstructural
parameters and macroscopic mechanical response of high temperature
composites. Such relationships would permit dependable engineering of
composite structural components for safe and reliable service at
elevated temperatures. We are conducting experimental and theoretical
work to study the significant issues on mechanisms and mechanics of
deformation and fracture of high temperature composites.
- In-Situ Reinforced
Composites
We are developing
several high temperature materials with an industrial collaborators,
such as Cr(Mo)/NiAl eutectic composite and oxide/oxide eutectic fibers
(Y3Al5O12/Al2O3
and Al2O3/ZrO2(Y2O3))
using the directional solidification technique. Currently, we are
conducting experimental work to study the kinetics and mechanisms of
microstructural instability as well the creep and strength degradation
deformation mechanisms.
- Processing and
Characterization of Nanoceramic and Composites
We are investigating the
sintering and mechanical behavior of nano-sized Si3N4
and SiC for high temperature applications.
