Symposium on Characterization and Representation of Materials Microstructures in 3D Foreword Progress with instrumentation and computing capabilities has recently brought new emphasis to a historical challenge in materials science: that of characterization, quantification, and representation of the materials structure in three-dimensions (3D). In this context material structure is intended to mean not only morphological and topological information, but also chemical and crystallographic information at various dimensional scales. The common practice is to examine two-dimensional planar sections of a material microstructure (indeed our profession is all but defined by the knowledge discovered by such techniques) and then to make inferences about the true morphology, distribution or connectivity of microstructural elements using stereological procedures and theorems. However, the need for inference can be alleviated and the information fidelity can be expanded if one can obtain a direct 3D volume sampling of the material microstructure. In the past decade there have been tremendous advances in both destructive and non-destructive techniques to capture 3D microstructural information from both organic and inorganic objects, and a host of methods now exist which allow one to characterize micro-constituents at a variety of length scales—from nanometer-size precipitates to millimeter-size grains. With the continued development of novel characterization instruments that provide a wealth of 3D data, there is also a need to address new methods to analyze or represent such information in a quantitative manner, in forms amenable to interpretation by machines, and with appropriate linkages to modeling and simulation environments. This collection of papers was presented at a recent TMS symposium that was held during the TMS Fall Meeting in Columbus, Ohio during October 2002. These papers highlight various aspects of the state-of-the-art in 3D characterization, as well as new methods for microstructural analysis and representation. We believe they represent an important first step toward bringing focus to this fundamentally new capability that is a major evolutionary advance of our profession. Michael D. Uchic Milo V.
