This book was released on 1967 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several experimental techniques are used to study the mechanisms of stress-corrosion cracking in high purity aluminum alloys. The effect of metallurgical variables such as alloying elements (Cr, Ag, Cu) and heat treatments on a 4.2Zn-3.3Mg aluminum alloy are determined. Techniques used in this study include electrode polarization, autoradiographic studies, microstress studies, electron microscopy (replica and transmission), metioscopy, and standard stress-corrosion testing methods. As a result of these studies, an electrochemical theory for the mechanism of stress-corrosion cracking which involves the strain induced absorption of hydrogen is found to be consistent with the observations.

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).

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.

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.

Download or read book Studies of Stress Corrosion Crack Growth in Al Zn Mg Alloys by the Double Torsion Method written by TL. Bond and published by . This book was released on 1984 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The double torsion test specimen was evaluated to determine if it was suitable for use in subcritical crack growth studies of ductile engineering alloys. Several attractive features of the double torsion specimen were observed, including a simple, crack-length-independent expression for stress intensity and the apparent retention of plane-strain conditions in relatively thin plate specimens. Use of the double torsion specimen to determine V-K curves for high-strength aluminum alloys in a chloride environment produced conventional two-stage growth, plateau velocities being slightly higher than those observed in similar tests using conventional plan strain specimens. The double torsion specimen appears attractive for subcritical crack growth studies under plane-strain conditions, particularly in the Stage II regime where crack velocities are not strongly dependent on stress intensity.

Download or read book On the Chemistry of the Solution at the Tips of Stress Corrosion Cracks in Aluminum Alloys written by A. J. Sedriks and published by . This book was released on 1970 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the factors affecting the change of pH with time of initially acidic (pH = 0 to 2) 3% NaCl solutions, resulting from the dissolution of turnings of a commercial 7075 alloy, an Al-5.3 wt. pct. Zn-2.5 wt. pct. Mg alloy, and pure aluminum. It was shown that for solutions containing large volume fractions of the solids, a steady pH is attained which is associated with the onset of precipitation of Al(OH)3. It is suggested, by analogy, that the formation of the steady pH region at the tips of stress-corrosion cracks in aluminum alloys is also associated with the onset of precipitation of Al(OH)3, and that the pH in this region can be calculated from the solubility product of freshly precipitated Al(OH)3. The study also suggests that similar conclusions apply to the stress-corrosion cracking of magnesium alloys. (Author).
