Download or read book Investigation to Improve the Stress Corrosion Resistance of Aluminum Aircraft Alloys Through Alloy Additions and Specialized Heat Treatment written by J. T. Staley and published by . This book was released on 1969 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to develop a high-strength aluminum alloy resistant to stress-corrosion cracking in the short-transverse direction. The alloys investigated included a 7075 control, 7075 type alloys which contained either 0.3% Mn or 0.1% Zr in place of 0.2% Cr, similar alloys which also contained 0.3% Ag, and chromium-bearing alloys which contained either higher zinc or higher copper than the maximum amounts specified for 7075. These materials were evaluated as two-inch thick plate to insure that the structures would be representative of thick, hot-worked products. (Author).

This book was released on 1970 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program was to develop a high-strength aluminum alloy resistant to stress-corrosion cracking in the critical short-transverse direction. The alloys investigated include a 7175 control and Al-Zn-Mg-Cu alloys containing 5.8 to 7.4% Zn, 2.0 to 2.5% Mg, and 2.1 to 2.7% Cu along with either separate or combined additions of Zr, Mn, and Cr. They were fabricated from large ingots to two-inch thick plate to insure that the structures would be representative of thick, hot-worked products. All of the experimental alloys developed more attractive combinations of strength and hardenability than the 7175 control along with promising resistance to stress-corrosion cracking. Moreover, most of them developed short-transverse elongation values equal to or higher than that of 7175 on an equivalent strength basis after solution heat treatment times long enough to dissolve substantially all of the Al2CuMg particles. Alloys which contained 5.75-6.75% Zn, 2.0-2.5% Mg, 2.1-2.6% Cu, .09-.15% Zr, .12% max. Fe, and .10% max. Si developed the most attractive combination of properties. (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).

This book was released on 1996-03-29 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.

This book was released on 1986 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 6 of Research on Technological Innovation, Management and Policy contains five papers on strategic change in firms and industries. All five discuss aspects of the interrelationships between technology strategy, competitive strategy, and organization and management. The first two address these at a level of the industry; the next two at firm level; in the final chapter, the level of analysis is primarily the technology. These five chapters are illustrative of themes in current research that are shaping the field of strategic management technology and innovation. They build well on earlier work in the field and thereby support its further empirical and theoretical development. They also provide useful insights for practicing managers faced with the challenges of changing technologies and a rapid rate of innovation.
