Book Description
An attempt was made to determine the mechanisms of deformation and fracture in polycrystalline Cd, to correlate these mechanisms with pertinent aspects of single crystal behavior, and to determine whether the slip systems and mode of fracture of polycrystalline Cd could be altered by reduction of the axial ratio (1.886) byALLOYING. Tests on polycrystalline Cd and Cd-Mg alloys indicated that the yield stress, flow stresses for arbitrary small strains, and the average coefficient of work hardening were relatively insensitive to temperature from room temperature to 4.2 K. The tensile strength of Cd was strongly temperature dependent but relatively independent of grain size between room temperature and -175C; below-175C it was dependent on grain size, but not on temperature. Cd had a ductile to quasi-brittle transition at about -155C which did not depend on grain size or purity. The minimum ductility, about 15% reduction in area, was reached near -196 and persisted at -269C.

Book Description
The use of magnesium alloys is increasing in a range of applications, and their popularity is growing wherever lightweight materials are needed. This book provides a comprehensive account of the corrosion of magnesium alloys. It covers not only the corrosion performances and mechanisms of Mg alloys in conventional environments, such as sodium chloride solutions, but also looks at their corrosion behaviours in special media, like engine coolants and simulated body fluids.Part one covers fundamentals such as the corrosion electrochemistry, activity and passivity of magnesium and its alloys. Part two then considers the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements, the corrosion behaviour of magnesium-based bulk metallic glasses, and the corrosion of innovative magnesium alloys. Part three goes on to describe environmental influences on the corrosion of magnesium alloys, such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion. Finally, part four is concerned with various means of protecting magnesium alloys against corrosion through the use of aluminium electrodeposition, conversion and electrophoretic coatings, and anodisation.With its distinguished editor and team of contributors, this book is an invaluable resource for metallurgists, engineers and designers working with magnesium and its alloys, as well as professionals in the aerospace and automotive industries. - Provides a comprehensive account of the corrosion of magnesium alloys covering fundamentals such as the corrosion electrochemistry, activity and passivity - Reviews the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements - Assesses environmental influences such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion
