ABSTRACT
This proposal seeks to build the foundation for an intrinsic long-tenn improvement in the
materials research capabilities at the University of Kentucky through the acquisition of an
advanced Field Emission Gun Scanning Electron Microscope (FEGSEM) with Electron Back
Scatter Diffraction (EBSD) and Energy Dispersion Spectroscopy (EDS) equipped with the
necessary attachments to support macro- and micro-texture, nano-scale imaging and composition
analysis experiments. The FEGSEM-EBSD-EDS will support both ongoing and future materials
research that is of interest to the Department of Defense. Furthennore, it will enhance materials
science education at the University of Kentucky while stimulating new areas of research that are
of interest to the DOD.
Current DOD-funded research projects at the University of Kentucky that will immediately
benefit from the new instrumentation include: (1) Residual Stress, Macro- and Micro-Texture,
and High-Cycle Fatigue in Surface Enhanced Titanium Alloys; (2) Prediction of Texture and
Fonnability of Continuous Cast AA 5000 and 2000 Series Aluminum Alloy Sheets and Their
Quality Improvement. The first project is supported by the Directorate of Mathematics and Space
Sciences at AFOSR, the main objectives of which are: (i) to develop an ultrasound technique for
nondestructive inspection of the profile of residual stress induced by the surface-enhancement
technique of low plasticity burnishing; (ii) to understand the changes of microstructure and
texture due to surface-enhancement treatments and their effects on the high cycle fatigue
properties of Ti alloys. The second project is sponsored by the Directorate of Aerospace and
Materials Sciences at AFOSR and has Commonwealth Aluminum Concast, Inc., as industrial
partner. Its main goal is to develop continuous cast 2000 series aluminum alloys and
quantitatively predict crystallographic texture and fonnability of these alloys for possible
aerospace applications. The proposed FEGSEM-EBSD-EDS will allow the PIs to conduct
experiments in house that will complement ongoing theoretical and computational efforts.
