DOWNLOAD EBOOKTreatise on Materials Science and Technology, Volume 25: Embrittlement of Engineering Alloys is an 11-chapter text that describes some situations that produce premature failure of several engineering alloys, including steels and nickel- and aluminum-base alloys. Chapters 1 to 3 consider situations where improper alloy composition, processing, and/or heat treatment can lead to a degradation of mechanical properties, even in the absence of an aggressive environment or an elevated temperature. Chapters 4 and 5 examine the effect of elevated temperatures on the mechanical properties of both ferrous and nonferrous alloys. Chapters 6 and 7 discuss the effects of corrosive environments on both stressed and unstressed materials. In these environments anodic dissolution is the primary step that leads to failure. Chapters 8 to 10 deal with the effects of aggressive environments that lead to enhanced decohesion or embrittlement of the metal, such as hydrogen, liquid metal, and irradiation-induced embrittlement. Chapter 11 looks into the embrittlement phenomena occurring during welding, one of the most common processing conditions to which a material could be subjected. This book will prove useful to materials scientists and researchers.

DOWNLOAD EBOOKBonding Theory for Metals and Alloys, 2e builds on the success of the first edition by introducing new experimental data to each chapter that support the breakthrough "Covalon" Conduction Theory developed by Dr. Wang. Through the recognition of the covalent bond in coexistence with the 'free' electron band, the book describes and demonstrates how the many experimental observations on metals and alloys can all be reconciled. Subsequently, it shows how the individual view of metals and alloys by physicists, chemists and metallurgists can be unified. This book covers such phenomena as the Miscibility Gap between two liquid metals, phase equilibrium, superconductivity, superplasticity, liquid metal embrittlement, and corrosion. The author also introduces a new theory based on 'Covalon' conduction, which forms the basis for a new approach to the theory of superconductivity. Bonding Theory for Metals and Alloys, 2e is of interest to physical and theoretical chemists alongside engineers working in research and industry, as well as materials scientists, physicists, and students at the upper undergraduate and graduate level in these fields. All chapters completed revised to reflect developments in research since 2005 New experimental data added to each chapter Broadens experimental data to support the author’s "Covalon" conduction theory, which carries current in covalent bonded pairs Total of approximately 30% - 35% new and revised content

DOWNLOAD EBOOKThe Corrosion Resistant Metals Committee and the Nuclear Metallurgy Committee of the Institute of Metals Division of The Metallurgical Society of AlME sponsored a 2-1/2 day symposium on "Corrosion by Liquid Metals". The symposium was held in Philadelphia, October 13-15, 1969, during the 1969 Fall Meeting of the Metallurgical Society and the Materials Engineering Con gress of the American Society for Metals. Cosponsors included the American Society for Metals and the American Nuclear Society. The purpose of the symposium was to bring together the several aspects of the subject of corrosion by liquid metals, so that perspective could be provided on the entire subject, to help in dividuals dealing with liquid metal corrosion problems acquire a sound basis of understanding, and to provide an opportunity for discussion between those doing research in this field. An exposition of the subject is timely, in view of the in creasing development of liquid metal heat and power sources for special purposes, including heat-pipe systems, NASA's SNAP power systems, and the AEC's liquid metal fast breeder reactor system. This book contains the proceedings of the symposium divided into four separate topics: I. Corrosion of Steels by Sodium, II. Alkali-Refractory Metal Interactions, III. Corrosion by Non-Alkali Metals, and IV. Analysis of Solid-Liquid Metal Inter actions (two sessions).

DOWNLOAD EBOOKMetallographic and fractographic observations of sub-critical crack growth in a precipitation-hardened AlZn-Mg alloy in liquid-metal, aqueous, and water-vapour/air environments suggest that stress-corrosion cracking and liquid-metal embrittlement in this alloy involve a common mechanism. Sub-critical crack growth in all these environments can produce entirely dimpled fracture surfaces and, in liquid-metal and aqueous environments, crack growth can occur extremely rapidly. It is proposed that stress-corrosion cracking and liquid-metal embrittlement in aluminium alloys (and possibly other materials) can be explained on the basis that chemisorption of environmental species facilitates nucleation of dislocations at crack tips. Such a process would produce sub-critical crack growth with less blunting at crack tips than in inert environments and, hence, would explain observations that dimples on fracture surfaces after SCC are smaller and shallower than those on overload fractures. The results suggest that neither dissolution nor hydrogen-embrittlement processes occurred during stress-corrosion cracking in aluminium alloys. (Author).

DOWNLOAD EBOOKGrain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious phenomena which evoke these limitations is the grain boundary segregation of impurities. It results in the loss of grain boundary cohesion and consequently, in brittle fracture of the materials. The current book deals with fundamentals of grain boundary segregation in metallic materials and its relationship to the grain boundary structure, classification and other materials properties.
