Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to determine the effect of silver addition on the stress corrosion resistance of Al-Zn-Mg-Cu alloys. Tests were conducted by alternate immersion in 3 1/2% NaCl on two lots from two different sources. The silver bearing alloys displayed an increased susceptibility to pitting corrosion and a predominantly transgranular mode of cracking. No significant improvement in stress corrosion behavior was noted with silver addition as measured by time to cracking. (Author).

This book was released on 1967 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program is to develop a stress corrosion resistant high strength aluminum alloy through addition of minor elements and variations in heat treatment. In Phase I, fifteen special chemistry alloys based on the 7075 composition were prepared in plate form with additions of silver, boron, cerium, yttrium and zirconium. The materials evaluation consisted of metallographic and aging studies, stress corrosion testing and determination of mechanical and fracture properties. The silver bearing alloys, while not immune, were the only alloys to show increased resistance to stress corrosion cracking in the T6 temper. Overaging treatments improved the stress corrosion resistance of all alloy combinations tested. Mechanical property evaluations and transmission electron microscopy studies indicate that silver additions retard the rate of overaging and promote a finer dispersion of M' precipitate, which allow these materials to attain stress corrosion resistance without large decreases in tensile strength. However, the increased quench sensitivity of silver-bearing alloys may limit this strength advantage to thinner sections unless other changes are made in chemical composition. On the basis of stress corrosion, fatigue, fracture toughness, and strength requirements, five step-aged special chemistry alloys are proposed for Phase II testing. (Author).

Download or read book Effect of Silver Addition on Mechanical Properties and Stress Corrosion Cracking in a Predeformed and Overaged 7055 Aluminum Alloy written by Mehdi Shakouri and published by . This book was released on 2018 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of silver on mechanical properties and stress corrosion cracking (SCC) resistance in a predeformed and overaged 7055 aluminum alloy was investigated. The treatment consisted of solution treating the specimens and then applying 5 % plastic deformation (compression) before aging. The next operation was aging the specimens at 121°C for 24 hours and overaging them at 175°C for 10 hours. Properties of the alloys were investigated by mechanical testing, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and differential scanning calorimetry. Results show that the ultimate tensile strength (UTS) and yield tensile strength (YTS) for the silver-free alloy were 580 and 520MPa, respectively, and increased to 594 and 567MPa after the addition of 0.39 % silver. Moreover, the stress corrosion resistance increased = 23 % after adding 0.2 % silver. It can be seen that the addition of silver to predeformed and overaged 7055 aluminum alloy slightly improves the UTS and YTS and increases resistance to SCC significantly. These improvements are due to the interrupting effect of silver on the continuity of magnesium-rich precipitates and the increasing copper absorption in the precipitates.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the structure and properties of the current and potential aluminum alloys in terms of their structure (and structural transformations by new processing methods) and the relationship between structure and mechanical and other properties. The alternative materials that challenge aluminum are considered as well, since the challenge of new competitive materials is a strong influence on innovation. The book bridges the gap between current scientific understanding and engineering practice. It is an up-to-date reference that will be of use to researchers and advanced students in metallurgy and materials engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Although a number of investigations of the bearing strength of aluminum alloys have been made, the problem remains one of considerable interest to the aircraft industry. For this reason it has seemed advisable to make additional tests of the commonly used aircraft alloys in an effort to establish a better basis for the selection of allowable bearing values. Current design practice does not recognize the effect of edge distance upon bearing strengths, and for this reason edge distance upon bearing strengths, and for this reason edge distance was one of the principal variables considered in this investigation. The increasing emphasis being placed upon permanent set limitations makes it essential that more information on bearing yield phenomena be obtained.
