A Quantum Approach to Alloy Design: An Exploration of Material Design and Development Based Upon Alloy Design Theory and Atomization Energy Method presents a molecular orbital approach to alloy design that is based on electronic structure calculations using the DV-X alpha cluster method and new alloying parameters obtained from these calculations. Topics discussed include alloy properties, such as corrosion resistance, shape memory effect and super-elasticity that are treated by using alloying parameters in biomedical titanium alloys. This book covers various topics of not only metals and alloys, but also metal oxides, hydrides and even hydrocarbons. In addition, important alloy properties, such as strength, corrosion resistance, hydrogen storage and catalysis are treated in view of electron theory. Presents alloy design theory and the atomization-energy method and its use for the fundamental understanding of materials and materials design and development Discusses, for the first time, the atomization-energy analysis of the local lattice strains introduced around alloying elements in metals Illustrates a simplified approach to predict the structure and phases stability of new alloys/materials

This is the only book to cover the most recent developments in applied quantum theory and their use in modeling materials properties. It describes new approaches to modeling disordered alloys and focuses on those approaches that combine the most efficient quantum-level theories of random alloys with the most sophisticated numerical techniques. In doing so, it establishes a theoretical insight into the electronic structure of complex materials such as stainless steels, Hume-Rothery alloys and silicates.

One of the ultimate goals of materials research is to develop a fun damental and predictive understanding of the physical and metallurgical properties of metals and alloys. Such an understanding can then be used in the design of materials having novel properties or combinations of proper ties designed to meet specific engineering applications. The development of new and useful alloy systems and the elucidation of their properties are the domain of metallurgy. Traditionally, the search for new alloy systems has been conducted largely on a trial and error basis, guided by the skill and intuition of the metallurgist, large volumes of experimental data, the principles of 19th century thermodynamics and ad hoc semi-phenomenological models. Recently, the situation has begun to change. For the first time, it is possible to understand the underlying mechanisms that control the formation of alloys and determine their properties. Today theory can begin to offer guidance in predicting the properties of alloys and in developing new alloy systems. Historically, attempts directed toward understanding phase stability and phase transitions have proceeded along distinct and seemingly diverse lines. Roughly, we can divide these approaches into the following broad categories. 1. Experimental determination of phase diagrams and related properties, 2. Thermodynamic/statistical mechanical approaches based on semi phenomenological models, and 3. Ab initio quantum mechanical methods. Metallurgists have traditionally concentrated their efforts in cate gories 1 and 2, while theoretical physicists have been preoccupied with 2 and 3.

FUNDAMENTAL ASPECTS OF STRUCTURAL ALLOY DESIGN is the proceedings of the tenth Battelle Colloquium in the Materials Sciences, held in Seattle, Washington, and Harrison Hot Springs, B.C., September 15-19, 1975. The theme of the conference was the emerging science of alloy design. Although the relationships of properties of alloys to their composition and structure have long been a dominant theme in physical metallurgy, it is only recently that metallurgists have turned their attention from the analytical, post hoc study of the structure-property relationship to the synthesis approach of alloy design. As usual in the Battelle colloquia, the first day started with a group of introductory lectures presented by leaders in the field, each emphasizing his personal approach to the problem. This provided a historical perspective for the colloquium. These papers, together with the banquet address of Professor J. R. Low, Jr., who was honored at the colloquium, comprise the introductory section of these proceedings. Alloy design is generally specific to a given application. Thus, the needs in alloy design in a number of important applications, gas turbines, electrical-power-generation equipment, airframes, pressure vessels, and nuclear applications were presented in a group of papers. An agenda discus sion on "Needs in Alloy Design" followed. These papers give the external constraints on alloy design applications, and criteria for mechanical, physical, and chemical properties for which the alloys must be designed.

Metallurgy and Design of Alloys with Hierarchical Microstructures covers the fundamentals of processing-microstructure-property relationships and how multiple properties are balanced and optimized in materials with hierarchical microstructures widely used in critical applications. The discussion is based principally on metallic materials used in aircraft structures; however, because they have sufficiently diverse microstructures, the underlying principles can easily be extended to other materials systems. With the increasing microstructural complexity of structural materials, it is important for students, academic researchers and practicing engineers to possess the knowledge of how materials are optimized and how they will behave in service. The book integrates aspects of computational materials science, physical metallurgy, alloy design, process design, and structure-properties relationships, in a manner not done before. It fills a knowledge gap in the interrelationships of multiple microstructural and deformation mechanisms by applying the concepts and tools of designing microstructures for achieving combinations of engineering properties—such as strength, corrosion resistance, durability and damage tolerance in multi-component materials—used for critical structural applications. Discusses the science behind the properties and performance of advanced metallic materials Provides for the efficient design of materials and processes to satisfy targeted performance in materials and structures Enables the selection and development of new alloys for specific applications based upon evaluation of their microstructure as illustrated in this work

Computational materials science is a comparatively new discipline that may forever alter the way in which materials are made and improved. This discipline seeks to use modeling and simulation to predict the properties of materials that have yet to be made. it is hoped that the ever-increasing power of computation can be harnessed to aid the materials designer and thereby accelerate the pace and reduce the cost of materials development. Because the objective of this new discipline is to aid in the design of materials, its advancement does not rely exclusively on increasingly sophisticated computational models. This advancement also requires the integration of these with traditional approaches to materials design, which make use of processing-structure-property relationships. It is argued here that the established descriptions of molecular structure and bonding can not be placed in the form of processing-structure-property relationships. Before quantum mechanical methods can be used in the discovery of such relationships, a new way to describe bonding is required. In this AFOSR funded program, such a description of the chemical bond was developed. It was shown, for specific phenomena, this new description could be used to construct processing-structure-property relationships. As these relationships were studied, it became evident that intrinsic mechanical properties are controlled by well-characterized boundaries that separate one bond from another. An understanding of how these boundaries move in response to an applied strain is necessary before it will be possible to uncover generalized relationships between the quantum mechanically determined charge density and mechanical properties.
