ABSTRACT --- Two dimensional and three-dimensional microstructures of as-cast and
hot-deformed 6063 aluminum were obtained via Light-Optical-Microscopy (LOM) and
Electron-Back-Scatter-Diffraction (EBSD) at the Institute for Metal Forming at Lehigh
University. These microstructures were used as the seed structure for textureprediction
software developed at Rensselaer Polytechnic Institute, and for verification
of the final simulated deformed structure and crystallographic pole-plots. Techniques
for obtaining three-dimensional microstructures and for quantifying them into 3-D
datasets useful for Finite Element Modeling (FEM) analyses are discussed. Similar
techniques for acquiring the topology and distribution of α - and β -precipitates within
the three-dimensional grain morphologies are also discussed.
