The choice of a material for a certain application is made taking into account its properties. If, for example one would like to produce a table, a hard material is needed to guarantee the stability of the product, but the material should not be too hard so that manufacturing is still as easy as possible - in this simple example wood might be the material of choice. When coming to more advanced applications the required properties are becoming more complex and the manufacturer`s desire is to tailor the properties of the material to fit the needs. To let this dream come true, insights into the microstructure of materials is crucial to finally control the properties of the materials because the microstructure determines its properties.
Written by leading scientists in the field of microstructural design of engineering materials, this book focuses on the evolution and behavior of granular microstructures of various advanced materials during plastic deformation and treatment at elevated temperatures. These topics provide essential background and practical information for materials scientists, metallurgists and solid state physicists.

Preface
Properties of crystalline engineering materials are directly related to their microstructure, defined as the spatial distribution of elements, phases, defects, and orientations. In view of the dramatically increased specific property material requirements during the past decades, the efforts to understand how the granular microstructure of polycrystals develops and how it can be influenced and predicted became extremely important, since microstructure control is crucial, both for improvement of materials performance and design of advanced materials with tailored properties.
The topic of microstructural design of advanced materials was recently the focus of a special symposium,1 in honor of Professor Dr rer. nat. Dr h.c. Günter Gottstein (Günter Gottstein Honorary Symposium on Characterization and Design of Microstructure for Advanced Materials), which was held in the frame of the MSE 2012 (Materials Science and Engineering) Congress in Darmstadt, Germany, September 25–27, 2012, organized by the Deutsche Gesellschaft für Materialkunde (DGM).
This book represents a collection of manuscripts written by leading scientists in the field of microstructural design of engineering materials, who were invited to deliver keynote lectures at the Günter Gottstein Honorary Symposium. This provided a unique opportunity to bring together experts in various aspects of microstructure design and to address a wide range of topics, which are crucial for predicting and controlling the microstructure evolution, including crystal plasticity due to slip, twinning, and grain boundary motion; nucleation during recrystallization; grain boundary migration under various forces; impact of boundary junctions; interfacial anisotropy and solute segregation, interaction between interfaces and particles, and so on. As obvious from the reviews comprising this book, an interaction between various research approaches – experiment, microstructural modeling, computation, and theory – is indispensable for successful and effective microstructural design of advanced engineering materials.
The book is subdivided into four parts, beginning with the modeling of the basic processes of microstructure development, that is, crystal plasticity, deformation, and recrystallization in different metallic materials subjected to various processing routes including severe plastic deformation. The second part addresses grain boundaries and interfaces, their kinetics and thermodynamics, and their effects on microstructure evolution. The third part is dedicated to advanced experimental methods to characterize the microstructure and to elucidate the underlying mechanisms of its development. The final chapters comprise various applications – grain boundary engineering for improving fracture resistance of various metals and alloys and microstructural design of advanced high temperature materials.
The editor is grateful to all authors for their engagement and cooperation as well as the Wiley-VCH editorial team for the enthusiasm and help to prepare and publish this book and in such a way to celebrate Professor Günter Gottstein and his unique contributions to Materials Science.

Through-Process Modeling of Materials Fabrication: Philosophy, Current State, and Future Directions
Günter Gottstein
Mathematical modeling of physical phenomena is not new science or a recent development but a fundamental ingredient of physical sciences. In fact, mathematics is the language of natural sciences, and it is the objective of physical research to extract from observed phenomena the general behavior in terms of mathematical relations that will allow making quantitative predictions. Physical phenomena are usually described in terms of respective equations of state (thermodynamic considerations) and equations of motion (kinetic considerations). Both types of relations are typically expressed in terms of differential equations, mostly partial differential equations (PDEs). The solution of these equations for usually complex boundary conditions can most commonly not be obtained in closed form, and therefore, the behavior of respective thermodynamic or kinetic systems can only be determined for very special conditions, for example, at the limits of time and space. Forty years ago, owing to the lack of easy to handle closed form solutions particularly engineers refrained from utilizing physics-based concepts, but instead they developed empirical models by fitting simple mathematical functions to obtained data, mostly power law relations for monotonic dependencies, since a power law could still be handled by a slide rule, the typical personal computational tool at that time. Such empirical approaches were actually very accurate as long as the same material was processed the same way, but beyond measured regimes they lacked any predictive power.
With the advent of powerful computers, the situation changed dramatically. Besides the fact that complicated PDEs and complex boundary conditions could now be solved numerically, simulation tools became available to probe virtual materials behavior at any length and time scale. On the macroscopic scale the finite element method (FEM) became the predominant numerical tool for engineers; on the mesoscopic level, the phase-field theory besides Monte Carlo (MC) methods, cellular automata (CA), and front tracking algorithms such as vertex models or level-set methods advanced to established modeling approaches for microstructural evolution of materials. On the atomistic level molecular dynamics (MD) simulations enabled a large variety of atomistic phenomena to be explored, and eventually density functional theory allowed ab-initio quantum mechanical studies of complex atomistic configurations, to name only the most popular approaches. With these computational tools at hand, one does not generate new physics, since the models and tools essentially reflect our understanding of physical phenomena and the underlying mechanisms. Instead, available computational power allows us to address complex phenomena, mutual interaction of different physical processes, and nonsteady-state behavior of physical systems. If we confine our consideration to materials, in particular to crystalline solids, specifically commercial metallic materials, we have now the option to utilize computer power, sophisticated simulation approaches, and advanced numerical algorithms for the prediction of material properties and therefore, for an optimization of materials processing and materials performance in service, in other words we are now able to put 50 years of physical metallurgy to work.
To make reliable predictions of materials behavior one has to understand that, contrary to common believe of engineers, the properties of a material are not controlled by the processing conditions but by chemical composition and microstructure. In other words, there are no processing–property relationships that can be utilized for the prediction of material properties; rather the only state variable of properties is, besides the unchanged overall composition, the microstructure, which is liable to change by thermal and mechanical processing (). Hence, the prediction of final properties of a material requires to pursue the development of microstructure along the entire processing chain, in principle from solidification through the semifinished product and eventually to a part in service. The simulation of microstructure evolution and therefore of materials properties along the processing chain is referred to as through-process modeling (TPM) in Europe or, more recently, integrated computational materials engineering (ICME) in the United States. In the following, we will use throughout the term TPM, keeping the identity with ICME in mind.
