Realistic micromechanical modeling and simulation of two-phase heterogeneous materials
(Georgia Institute of Technology, 2008-05-19)
This dissertation research focuses on micromechanical modeling and simulations of two-phase heterogeneous materials exhibiting anisotropic and non-uniform microstructures with long-range spatial correlations. Completed ...
Microstructural effects on surface mechanical properties of ion-implanted polymers
(Georgia Institute of Technology, 1993-04)
Tefzel, a copolymer of tetrafluoroethylene and ethylene, was implanted simultaneously with 400 keV boron, 700 keV nitrogen, and 600 keV carbon to a dose of 3 X 10¹⁵ ions/cm² for each ion. The implanted layer was examined ...
Study of microstructure in SrTiO₃/Si by high-resolution transmission electron microscopy
(Georgia Institute of Technology, 2002-01)
Microstructure in the SrTiO₃/Si system has been studied using high-resolution transmission electron microscopy and image simulations. SrTiO₃ grows heteroepitaxially on Si with the orientation relationship given by ...

Link-up of 90° domain boundaries with interface dislocations in BaTiO₃/LaAlO₃
(Georgia Institute of Technology, 1996-05-27)
Interface microstructures of BaTiO₃/LaAlO₃ grown by metalorganic chemical vapor deposition(MOCVD) are studied using high-resolution transmission electron microscopy (HRTEM). Interface dislocations in BaTiO₃/LaAlO₃ have ...
Layered microdomains and columnar grains in epitaxial La₀.₇Ca₀.₃MnO₃ films and Y₀.₇Ca₀.₃MnO₃/La₀.₇Ca₀.₃MnO₃ multilayers
(Georgia Institute of Technology, 2000-11)
Epitaxial La₀.₇Ca₀.₃MnO₃ thin film and [Y₀.₇Ca₀.₃MnO₃/La₀.₇Ca₀.₃MnO₃]₁₀ multilayers of about 140 nm in thickness were grown by pulsed laser deposition on (001)LaAlO₃. Their microstructures were investigated by transmission ...
Microstructure-sensitive extreme value probabilities of fatigue in advanced engineering alloys
(Georgia Institute of Technology, 2010-07-07)
A novel microstructure-sensitive extreme value probabilistic framework is introduced to evaluate material performance/variability for damage evolution processes (e.g., fatigue, fracture, creep). This framework employs newly ...
Non-destructive Electrical Characterization of Controlled Waspaloy Microstructures
(Georgia Institute of Technology, 2007-04-06)
In this research, controlled Waspaloy microstructures were produced with the objective of studying microstructural evolution in this alloy via electrically-based ac/dc non-destructive techniques. Correlations were developed ...
