This book was released on 1968 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents significant test results showing that 0.3% silver additions to melts of certain aluminum casting alloys, 40E and Precedent 71A, increase the yield and tensile strengths without large loss of ductility. Yield strength improves 80% and tensile strength 45% in test-size castings of silver treated 40E alloy, after solution-precipitation treatment; yield and tensile strengths increase more than 13% each, in machined specimens from end-chilled plates. A one week delay between solution treatment and artificial aging of the standard 40E alloy improves the yield and tensile strengths more than 30% each, but no additional improvement occurs in the silver-treated alloy. After artificial aging only, test-size castings from the silver treated alloy increase more than 25% in yield and 10% in tensile strength; machined specimens from plates improve more than 15% in yield and 5% in tensile strength. Only marginal gain in yield strength occurs after natural aging for 40 days. Remelting of the alloy does not destroy the beneficial effects of silver additions. Silver improves the yield strength 5 to 10% in Precedent 71A alloy after solution-precipitation treatment. (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 report brings together under one cover the information available on an aluminum casting alloy designated M45 which consists primarily of aluminum admixed with copper, cadmium, magnesium, and titanium. M45 was designed specifically for use in cryogenic environments where materials of strength, ductility, and toughness are required. Because these properties of the material actually increase as temperatures decrease, M45 appears to be attractive for many applications at cryotemperatures."--Foreword.
