| Abstract Scope |
The discovery of X-rays 125 years ago enabled to reveal the internal structure of materials, as comprised by the spatial arrangement and distribution of elements as well as crystal defects, which we refer to as microstructure.
A fundamental paradigm of physical metallurgy relates material properties to microstructure besides alloy chemistry. Research in the past century has generated a framework to quantitatively link microstructure to material properties. Since microstructure development during processing of a material is a complex and highly nonlinear phenomenon, the non-empirical prediction of material properties from the knowledge of processing history became only feasible with the advent of high-power computers. However, microstructural evolution proceeds by atomistic processes, which requires a deep understanding of the underlying physical mechanisms.
This presentation will address essentials of respective approaches and challenges for microstructure modeling from conventional processing routes to increasingly complex material structures and modern material fabrication. |
