Very light, very strong. extremely reliable -aircraft and aerospace engineers are. and have to be. very demanding partners in the materials community. The results of their research and development work is not only crucial for one special area of applications. but can also lead the way to new solutions in many other areas of advanced technology. Springer-Verlag and the undersigned editor are pleased to present in this volume. an overview of the many facets of materials science and technology which have been the objective of intensive and systematic research work during past decades in the laboratories of the German Aerospace Research Establishment. Its contents shows clearly the interrelations between goals defined by the user. fundamentals provided by the scientists and viable solutions developed by the practical engineer. The particular personal touch which has been given to this volume by its authors in dedicating it as a farewell present to Professor Wolfgang Bunk. inspiring sci entist and director of the DLR Intitute of Materials Research for more than 20 years. has obviously given an added value to this important publication. Surely. this truly cooperative endeavour will render a valuable service to a large interna tional community of interested readers. many of them having personal links to the Institute. its director and its staff.

This report summarizes discussions held with eight members of the newly organized Center for Advanced Aerospace Materials, which is supported by the Korea Science and Engineering Foundation. Although the majority of projects at the center do fall under the broad category of aerospace materials, some of the work is also aimed at the application of traditional aerospace materials to automotive and other applications. The largest amount of research is based on Al alloys such as the 7000 series, Al-Li alloys, and Rs Al alloys. Of note among this work is a high strength and weldable Mn-modified Al-Zn-Mg alloy which is being developed for commercialization. Other work of interest includes elemental PM-based gamma Ti-Al alloys, AlN fibers, whiskers and foams produced by SHS, and theoretical advancements in SPF. (MM).

The effect of microstructure, environment, and coatings on mechanisms of fatigue and fatigue crack initiation and growth in TiAl intermetallic alloys has been investigated. For a gamma titanium aluminide alloy, the coarse and refined lamellar materials with colony sizes equal to 700 and 280 micrometers, respectively, have substantially greater crack growth resistance than does the fine duplex material with approximately 20 micrometers grain size. The influence of laboratory air on a wrought gamma TiAl alloy produces crack growth rates more than an order of magnitude higher than those observed in ultra high vacuum environment at temperatures ranging from ambient to 800 deg C.A twophase glass coating that exhibits a reduction in oxidation rate of an orthorhombic titanium aluminide, which was used as the matrix in a composite, fails to produce any enhancement in fatigue life. An extensive investigation involving fatigue, fatigue crack growth, mechanisms, modeling, and metallurgy of titanium matrix composites (TMC) is being conducted. Life models for isothermal and thermomechanical fatigue and crack propagation have been developed using concepts based on the maximum fiber stress, life fraction for time and cycle dependent response, matrix stress-life behavior, and fiber bridging. A model was developed for deformation, damage evolution, and failure of unidirectional TMC under sustained load. Effects of heat treatments on tensile and creep behavior of an orthorhombic neat matrix and on several continuous SiC fibers have been evaluated. Thermally induced stresses and damage progression in ceramic matrix composites due to fatigue and fracture are being studied. In monolithic materials, effects of stress ratio on FCG in an Al-alloy in the absence of closure and prediction of residual stress in Ti-6Al-4V generated by laser shock peening have been investigated.

Advanced Composite Materials for Aerospace Engineering: Processing, Properties and Applications predominately focuses on the use of advanced composite materials in aerospace engineering. It discusses both the basic and advanced requirements of these materials for various applications in the aerospace sector, and includes discussions on all the main types of commercial composites that are reviewed and compared to those of metals. Various aspects, including the type of fibre, matrix, structure, properties, modeling, and testing are considered, as well as mechanical and structural behavior, along with recent developments. There are several new types of composite materials that have huge potential for various applications in the aerospace sector, including nanocomposites, multiscale and auxetic composites, and self-sensing and self-healing composites, each of which is discussed in detail. The book’s main strength is its coverage of all aspects of the topics, including materials, design, processing, properties, modeling and applications for both existing commercial composites and those currently under research or development. Valuable case studies provide relevant examples of various product designs to enhance learning. Contains contributions from leading experts in the field Provides a comprehensive resource on the use of advanced composite materials in the aerospace industry Discusses both existing commercial composite materials and those currently under research or development

The structural materials used in airframe and propulsion systems influence the cost, performance and safety of aircraft, and an understanding of the wide range of materials used and the issues surrounding them is essential for the student of aerospace engineering.Introduction to aerospace materials reviews the main structural and engine materials used in aircraft, helicopters and spacecraft in terms of their production, properties, performance and applications. The first three chapters of the book introduce the reader to the range of aerospace materials, focusing on recent developments and requirements. Following these introductory chapters, the book moves on to discuss the properties and production of metals for aerospace structures, including chapters covering strengthening of metal alloys, mechanical testing, and casting, processing and machining of aerospace metals. The next ten chapters look in depth at individual metals including aluminium, titanium, magnesium, steel and superalloys, as well as the properties and processing of polymers, composites and wood. Chapters on performance issues such as fracture, fatigue and corrosion precede a chapter focusing on inspection and structural health monitoring of aerospace materials. Disposal/recycling and materials selection are covered in the final two chapters. With its comprehensive coverage of the main issues surrounding structural aerospace materials,Introduction to aerospace materials is essential reading for undergraduate students studying aerospace and aeronautical engineering. It will also be a valuable resource for postgraduate students and practising aerospace engineers.
