Available in PDF, EPUB and Kindle. Book excerpt: Abstract: To accurately predict microstructure evolution and, hence, to synthesis metal and ceramic alloys with desirable properties involves many fundamental as well as practical issues. In the present study, novel theoretical and phase field approaches have been developed to address some of these issues including solute drag and segregation transition at grain boundaries and dislocations, grain growth in systems of anisotropic boundary properties, and precipitate microstructure development in polycrystalline materials. The segregation model has allowed for the prediction of a first-order segregation transition, which could be related to the sharp transition of solute concentration of grain boundary as a function of temperature. The incorporating of interfacial energy and mobility as functions of misorientation and inclination in the phase field model has allowed for the study of concurrent grain growth and texture evolution. The simulation results were analyzed using the concept of local grain boundary energy density, which simplified significantly the development of governing equations for texture controlled grain growth in Ti-6Al-4V. Quantitative phase field modeling techniques have been developed by incorporating thermodynamic and diffusivity databases. The models have been validated against DICTRA simulations in simple 1D problems and applied to simulate realistic microstructural evolutions in Ti-6Al-4V, including grain boundary a and globular a growth and sideplate development under both isothermal aging and continuous cooling conditions. The simulation predictions agree well with experimental observations.

Available in PDF, EPUB and Kindle. Book excerpt: This book fills a gap by presenting our current knowledge and understanding of continuum-based concepts behind computational methods used for microstructure and process simulation of engineering materials above the atomic scale. The volume provides an excellent overview on the different methods, comparing the different methods in terms of their respective particular weaknesses and advantages. This trains readers to identify appropriate approaches to the new challenges that emerge every day in this exciting domain. Divided into three main parts, the first is a basic overview covering fundamental key methods in the field of continuum scale materials simulation. The second one then goes on to look at applications of these methods to the prediction of microstructures, dealing with explicit simulation examples, while the third part discusses example applications in the field of process simulation. By presenting a spectrum of different computational approaches to materials, the book aims to initiate the development of corresponding virtual laboratories in the industry in which these methods are exploited. As such, it addresses graduates and undergraduates, lecturers, materials scientists and engineers, physicists, biologists, chemists, mathematicians, and mechanical engineers.

This book was released on 2007 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical properties of engineering materials are directly controlled by the underlying microstructure, which in turn is governed by the processing methods. The complete description of microstructure is extremely complex and is also not required for many microstructure-properties relationships of interest. The relevant details of the microstructure that influence strongly the elastic-plastic properties of the material include the lattice orientation distribution (texture), the grain size and shape distribution, and the arrangement and distribution of dislocation networks on the various slip systems in the constituent crystals. Of these, the crystallographic texture is perhaps the most important aspect of microstructure that has a strong influence on the elastic and the initial yield properties of most polycrystalline materials used in the manufacture of engineering components. It should also be noted that crystallographic texture is likely to have the dominant effect on the inherent anisotropy exhibited by these materials.The objective of this thesis is to provide a mathematical framework for the development of material databases; capturing the relevant details of the microstructure, while paying attention to inherent anisotropy of properties associated with them. Here crystallographic texture is the only microstructural parameter that is considered. This work is motivated by a new design paradigm called microstructure sensitive design (MSD) which employs statistical description of microstructure and its core feature is the efficient spectral representations of microstructure-property-processing linkages. Using the MSD framework as the basis, novel computational methodologies were developed in this work to build material spectral databases in single phase cubic polycrystalline materials. These databases were critically evaluated in three different cases: 1) To predict the effective macroscale elastic properties in perfectly disordered copper polycrystals 2) Evolution of the microstructure and the concomitant anisotropic stress-strain response during deformation processes in FCC polycrystals and (3) in developing a processing recipe to obtain a targeted texture using selected processing techniques.
