Book Corrosion of Magnesium Alloys

Download or read book Corrosion of Magnesium Alloys written by G L Song and published by Woodhead Publishing. This book was released on 2011-03-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Stress corrosion Cracking of Aluminum Alloys

Download or read book Stress corrosion Cracking of Aluminum Alloys written by F. H. Haynie and published by . This book was released on 1966 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the stress-corrosion cracking of aluminum alloys, and it represents an effort by DMIC to expand on the information contained in DMIC Memorandum 202, 'Stress-Corrosion Cracking of Aluminum Alloys', dated February 15, 1965. DMIC Report 228 begins by presenting a comprehensive definition of stress-corrosion cracking. This is followed by sections dealing with (1) the historical development and growth in awareness of the problem, (2) the mechanisms involved, and (3) the theory of stress-corrosion cracking. A section on experimental techniques is presented. These techniques include test methods used to determine the susceptibility of alloys to stress-corrosion cracking, as well as more refined methods of studying the fundamental mechanisms of the problem. Different evaluation methods, applicable to obtaining the different objectives of stress-corrosion testing, are also presented. All of the foregoing serve as background to the sections on stress-corrosion-cracking behavior of aluminum alloys and preventive measures. (Author).

Book Stress Corrosion Cracking Behavior of Friction Stir Processed Ultrafine Grained Light Metal Alloys

Download or read book Stress Corrosion Cracking Behavior of Friction Stir Processed Ultrafine Grained Light Metal Alloys written by Gaurav Ramchandra Argade and published by . This book was released on 2012 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The influence of friction stir processing (FSP), a microstructural modification tool, on the corrosion behavior of Al-Mg, Al-Mg-Sc, Mg-Al-Zn and Mg-Y-RE alloys has been studied. An attempt has been made to establish correlation between processing parameters and the subsequent microstructural evolution especially matrix grain size on the corrosion and stress corrosion properties of the alloys. A relationship between grain size and corrosion rate for Mg-Y-RE alloys was envisaged and power law type behavior was proposed. Ultrafine fine grained (UFG) microstructure showed one order magnitude lower corrosion rate. Grain refinement achieved through different FSP parameters showed lower corrosion currents for Al-Mg alloy as compared to the base alloy. The significant increment in linear polarization resistance of UFG Al-Mg-Sc alloy has been attributed to modification in chemistry and grain refinement. The slow strain rate testing (SSRT) results indicated no stress corrosion susceptibility for FSP Al-Mg alloy. A critical grain size for Al-Mg alloys has been proposed to show optimum general corrosion resistance with no stress corrosion cracking (SCC) susceptibility. AZ31 microstructures showed significant loss of ductility during SSRT in corrosive medium indicating high SCC susceptibilities. The higher SCC resistance of over aged Mg-Y-RE microstructure as compared to under aged and peak aged was attributed to the alteration in microchemistry and precipitate morphology in the matrix"--Abstract, leaf iv.

Book Stress Corrosion Cracking of Al Zn Mg Alloys The Corrosion Behavior of Grain Boundary Constituents

Download or read book Stress Corrosion Cracking of Al Zn Mg Alloys The Corrosion Behavior of Grain Boundary Constituents written by A. J. Sedriks and published by . This book was released on 1972 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the grain-boundary constituents in Al-Zn-Mg alloys are generally too fine for their corrosion behavior to be studied in situ, an experimental approach involving simulation was adopted. This involved the examination of the corrosion behavior of a small ingot of MgZn2, the Al-Zn-Mg alloy in the as-quenched state, and pure aluminum. The pure aluminum and the as-quenched alloy were considered to represent the two limiting cases of the material comprising the precipitate-free zone; pure aluminum representing the limiting case of the solute-depleted region and the as-quenched alloy the vacancy depleted region.

Book Special Issues on Magnesium Alloys

Download or read book Special Issues on Magnesium Alloys written by Waldemar Alfredo Monteiro and published by BoD – Books on Demand. This book was released on 2011-09-12 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnesium is the lightest of all the metals and the sixth most abundant on Earth. Magnesium is ductile and the most machinable of all the metals. Magnesium alloy developments have traditionally been driven by requirements for lightweight materials to operate under increasingly demanding conditions (magnesium alloy castings, wrought products, powder metallurgy components, office equipment, nuclear applications, flares, sacrificial anodes for the protection of other metals, flash photography and tools). The biggest potential market for magnesium alloys is in the automotive industry. In recent years new magnesium alloys have demonstrated a superior corrosion resistance for aerospace and specialty applications. Considering the information above, special issues on magnesium alloys are exposed in this book: casting technology; surface modification of some special Mg alloys; protective carbon coatings on magnesium alloys; fatigue cracking behaviors of cast magnesium alloys and also, magnesium alloys biocompatibility as degradable implant materials.

Book Observations on the Stress Corrosion Cracking of an Al 5 Zn 2 5 MG Ternary and Various Quarternary Alloys

Download or read book Observations on the Stress Corrosion Cracking of an Al 5 Zn 2 5 MG Ternary and Various Quarternary Alloys written by J. A. S. Green and published by . This book was released on 1974 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were undertaken to test a concept of controlling stress-corrosion crack propagation in Al-Zn-Mg alloys through the use of minor alloying additions of elements known to retard hydrogen ion recombination such as Cd, As, Zr and Cr. Results indicated that the concept was invalid since the minor alloying additions themselves exerted a more profound influence on the grain boundary microstructure. Specifically, the microstructural features of grain boundary particle size and interparticle spacing were found to correlate with stress corrosion susceptibility. Auger electron spectroscope studies also revealed a correlation between the concentration of Zn and Mg within the precipitate-free zone and the susceptibility to cracking. (Modified author abstract).
