Dafei Kang, Jessica Shen and Hong Luo were selected from eight finalists
competing for the three slots.

Topic:
Microstructure, Properties and Deformation Mechanisms
of Nanostructured Al93Fe3Ti2Cr2 alloys
Abstract:
Nanostructured Al93Fe3Ti2Cr2 alloys were prepared via mechanical alloying and
extrusion. Its microstructure, thermal stability and mechanical properties were
studied. The MA-processed Al93Fe3Cr2Ti2 alloy is a promising material for high
temperature structural applications. Further studies will be focused on the TEM
observation and in-situ FESEM study to deduce the micro-mechanisms that control
the deformation process of the nc-Al93Fe3Ti2Cr2 alloy.
Speaker: Dafei Kang
Advisor: Dr. Mark Aindow
Bio: Having obtained his M. degree at the Dept. of Metallurgy and
Materials Engineering at UConn under the guidance of Prof. Mark Aindow, Dafei
Kang stays in Prof. Aindow's group and is currently a Ph.D. candidate working on
the characterization of heterogeneous supported catalysts using transmission
electron microscopy (TEM) and related techniques.
Topic: High-Resolution TEM Characterization of
Metal-Loaded Carbon Aerogels
Abstract:
This is a study by transmission electron microscopy (TEM) of carbon aerogels in
both pure form and with metal (ruthenium) loadings. Synthesized via a novel
supercritical carbon dioxide assisted sol-gel process, these carbon aerogels are
characterized with high porosity and surface area and therefore considered
excellent support for catalytic metal particles. In this study, the morphology
of both the tortuous carbon and the finely dispersed ruthenium nanoparticles
will be examined. Also discussed is an interesting transition of carbon aerogel
from disordered network to a more organized "onion-like" structure.

Topic: Thermal Barrier Coatings and Metallic
Coatings with improved Durability
Abstract:
Advanced industrial gas turbine engines require the use of reliable and highly
durable thermal barrier coatings (TBCs) and metallic coatings to meet the most
demanding high-temperature environment. In this program, the salient bond coat
composition and processing features were systematically investigated in order to
demonstrate the optimum combination of features that would provide the
improvement of durability and reliability. This study has demonstrated that the
composition distribution of the bond coat has a great impact on spallation
lifetime.
We are welcoming Mike Speciale, as representative of the New
England Air Museum, to this meeting to present to the Museum VHS and DVD
copies of "The Life and Death of the USS Hornet," a 16 mm
film of B-29's taking off from the USS Hornet for WWII bombing raids in the
Pacific. ASM Hartford is donating these copies to the New England Air Museum,
for use with their B-29
display, as a thank you gift for opening the Museum for our April 8, 2003
Materials Week event there.
