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

Understanding the electronic structure of solids is a basic part of theoretical investigation in physics. Application of investigative techniques requires the solid under investigation to be "periodic." However, this is not always the case. This volume addresses three classes of "non-periodic" solids currently undergoing the most study: alloys, surfaces and clusters. Understanding the electronic structure of these systems is fundamental not only for the basic science, but also constitutes a very important step in various technological aspects, such as tuning their stabilities, chemical and catalytic reactivities and magnetism. Expert practitioners give an up-to-date account of the field with enough detailed background so that even a newcomer can follow the development. The theoretical framework is discussed in addition to the present status of knowledge in the field. Electronic Structure of Alloys, Surfaces and Clusters also includes an extensive bibliography which provides a comprehensive reading list of work on the topic.

At present, there is an increasing interest in the prediction of properties of classical and new materials such as substitutional alloys, their surfaces, and metallic or semiconductor multilayers. A detailed understanding based on a thus of the utmost importance for fu microscopic, parameter-free approach is ture developments in solid state physics and materials science. The interrela tion between electronic and structural properties at surfaces plays a key role for a microscopic understanding of phenomena as diverse as catalysis, corrosion, chemisorption and crystal growth. Remarkable progress has been made in the past 10-15 years in the understand ing of behavior of ideal crystals and their surfaces by relating their properties to the underlying electronic structure as determined from the first principles. Similar studies of complex systems like imperfect surfaces, interfaces, and mul tilayered structures seem to be accessible by now. Conventional band-structure methods, however, are of limited use because they require an excessive number of atoms per elementary cell, and are not able to account fully for e.g. substitu tional disorder and the true semiinfinite geometry of surfaces. Such problems can be solved more appropriately by Green function techniques and multiple scattering formalism.

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.

The study of phase transformations in substitutional alloys, including order disorder phenomena and structural transformations, plays a crucial role in understanding the physical and mechanical properties of materials, and in designing alloys with desired technologically important characteristics. Indeed, most of the physical properties, including equilibrium properties, transport, magnetic, vibrational as well as mechanical properties of alloys are often controlled by and are highly sensitive to the existence of ordered compounds and to the occurrence of structural transformations. Correspondingly, the alloy designer facing the task of processing new high-performance materials with properties that meet specific industrial applications must answer the following question: What is the crystalline structure and the atomic configuration that an alloy may exhibit at given temperature and concentration? Usually the answer is sought in the phase-diagram of a relevant system that is often determined experimentally and does not provide insight to the underlying mechanisms driving phase stability. Because of the rather tedious and highly risky nature of developing new materials through conventional metallurgical techniques, a great deal of effort has been expended in devising methods for understanding the mechanisms contrOlling phase transformations at the microscopic level. These efforts have been bolstered through the development of fully ab initio, accurate theoretical models, coupled with the advent of new experimental methods and of powerful supercomputer capabilities.

The engineering of materials with advanced features is driving the research towards the design of innovative materials with high performances. New materials often deliver the best solution for structural applications, precisely contributing towards the finest combination of mechanical properties and low weight. The mimicking of nature's principles lead to a new class of structural materials including biomimetic composites, natural hierarchical materials and smart materials. Meanwhile, computational modeling approaches are the valuable tools complementary to experimental techniques and provide significant information at the microscopic level and explain the properties of materials and their very existence. The modeling also provides useful insights to possible strategies to design and fabricate materials with novel and improved properties. The book brings together these two fascinating areas and offers a comprehensive view of cutting-edge research on materials interfaces and technologies the engineering materials.
