Download or read book Effect of Thermal Exposure on the Tensile Properties of Aluminum Alloys for Elevated Temperature Service written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-15 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tensile properties were evaluated for four aluminum alloys that are candidates for airframe applications on high speed transport aircraft. These alloys included the Al-Cu-Mg-Ag alloys C415 and C416 and the Al-Cu-Li-Mg-Ag alloys RX818 and ML377. The Al-Cu-Mg alloys CM001, which was used on the Concorde SST, and 1143, which was modified from the alloy used on the TU144 Russian supersonic aircraft, were tested for comparison. The alloys were subjected to thermal exposure at 200 F, 225 F and 275 F for times up to 30,000 hours. Tensile tests were performed on thermally-exposed and as-received material at -65 F, room temperature, 200 F, 225 F and 275 F. All four candidate alloys showed significant tensile property improvements over CM001 and 1143. Room temperature yield strengths of the candidate alloys were at least 20% greater than for CM001 and 1143, for both the as-received and thermally-exposed conditions. The strength levels of alloy RX818 were the highest of all materials investigated, and were 5-10% higher than for ML377, C415 and C416 for the as-received condition and after 5,000 hours thermal exposure. RX818 was removed from this study after 5,000 hours exposure due to poor fracture toughness performance observed in a parallel study. After 30,000 hours exposure at 200 F and 225 F, the alloys C415, C416 and ML377 showed minor decreases in yield strength, tensile strength and elongation when compared to the as-received properties. Reductions in tensile strength from the as-received values were up to 25% for alloys C415, C416 and ML377 after 15,000 hours exposure at 275 F.

Download or read book Properties of Aluminum Alloys written by John Gilbert Kaufman and published by ASM International. This book was released on 1999-01-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compilation of data collected and maintained for many years as the property of a large aluminum company, which decided in 1997 to make it available to other engineers and materials specialists. In tabular form, presents data on the tensile and creep properties of eight species of wrought alloys and five species of cast alloys in the various shapes used in applications. Then looks at the fatigue data for several alloys under a range of conditions and loads. The data represent the typical or average findings, and though some were developed years ago, the collection is the largest and most detailed available. There is no index.

Available in PDF, EPUB and Kindle. Book excerpt: 100 years after the first observation of ripening by Ostwald and 40 years after the first publication of a theory describing this process, this monograph presents in a self-consistent and comprehensive manner, all the bits and pieces of coarsening theories so that the main issues and the underlying mathematics of self-similar coarsening of dispersed systems can be understood. Rather than giving a complete survey of the field, it presents a careful derivation of the existing results and places them into some perspective.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Examines characteristics of wrought and cast aluminum alloys, then presents basic aluminum alloy and temper designation systems, as developed by the Aluminum Association, and explains them with examples. Wrought and cast aluminum designations are treated in a similar fashion. Processes used to produce aluminum alloy products are described briefly, and representative applications for aluminum alloys and tempers are detailed, in areas such as electrical markets, building and construction, marine and rail transportation, packaging, and petroleum and chemical industry components. A final chapter presents 65 pages of bandw micrographs illustrating the microstructure of a range of aluminum alloys and tempers, to assist in understanding consequences of applying the production technology implied by the temper designations.
