Available in PDF, EPUB and Kindle. Book excerpt: The development of processes for making high-strength, high quality products from prealloyed atomized AL powders is described. High quality, high-strength 2 in. dia. heat treatable extrusions have been produced by aluminum powder metallurgy methods. Compacts were produced either by cold compacting-hot coining or by hot pressing of preheated powders. The tensile properties of the compacts after heat treating were lower than the heat treated 2 in. dia. extrusions. The properties of duplicate specimens also lacked the uniformity which was present for the extrusions. Cold compacted and sintered material had extremely low tensile properties. Forging and hot upsetting in a closed die have resulted in the tensile strengths being increased to approximately the level of extruded stock. Sheet produced from forged material also had high properties. The working temperature of these alloys is extremely important. Although the weldability of these alloys is better than the AL-Al2O3 alloys, the porosity is still too high for commercial use. (Author).
Download or read book Aluminum Lithium Alloys written by N Eswara Prasad and published by Butterworth-Heinemann. This book was released on 2013-09-20 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because lithium is the least dense elemental metal, materials scientists and engineers have been working for decades to develop a commercially viable aluminum-lithium (Al-Li) alloy that would be even lighter and stiffer than other aluminum alloys. The first two generations of Al-Li alloys tended to suffer from several problems, including poor ductility and fracture toughness; unreliable properties, fatigue and fracture resistance; and unreliable corrosion resistance. Now, new third generation Al-Li alloys with significantly reduced lithium content and other improvements are promising a revival for Al-Li applications in modern aircraft and aerospace vehicles. Over the last few years, these newer Al-Li alloys have attracted increasing global interest for widespread applications in the aerospace industry largely because of soaring fuel costs and the development of a new generation of civil and military aircraft. This contributed book, featuring many of the top researchers in the field, is the first up-to-date international reference for Al-Li material research, alloy development, structural design and aerospace systems engineering. - Provides a complete treatment of the new generation of low-density AL-Li alloys, including microstructure, mechanical behavoir, processing and applications - Covers the history of earlier generation AL-Li alloys, their basic problems, why they were never widely used, and why the new third generation Al-Li alloys could eventually replace not only traditional aluminum alloys but more expensive composite materials - Contains two full chapters devoted to applications in the aircraft and aerospace fields, where the lighter, stronger Al-Li alloys mean better performing, more fuel-efficient aircraft

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.

Download or read book Development of High Strength Wrought Aluminum Base Alloys written by S. N. Singh and published by . This book was released on 1967 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Work is reported on small-scale laboratory techniques for development of high strength wrought aluminum alloys, and on structure and properties of alloys produced. Highest tensile strengths obtained were in excess of 115,000 psi; highest yield strengths were in excess of 110,000 psi. Four different alloys tested showed yield strengths in excess of 90,000 psi with elongations in excess of 5%. All testing was on flat specimens machined from rolled sheet. The sheet was produced from cast ingots. The ingots employed as starting material were thin section rapidly solidified plates. The rapid solidification produced a dendrite arm spacing that was sufficiently fine (approximately 8 microns) that complete homogenization was feasible in a reasonable time. Plates were fully homogenized before rolling. In initial stages of the alloy development, a levitation melting and 'splat cooling' device was used to permit rapid determination of (1) maximum alloy contents that could be employed while still retaining a single phase at solution temperature, and (2) optimum solution treatment temperature. Dendrite arm spacing in these splats was 1-2 microns. (Author).

Download or read book The Development of Aluminum 6 Per Cent Magnesium Wrought Alloys for Elevated temperature Service and Their Resistance to Corrosion in Water at Temperatures Up to 6000F written by K. Grube and published by . This book was released on 1950 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the present time, 28 aluminum and 728 are used in applications in which river water attains temperatures as high as about 180 deg F. The 2S is aluminum of commercial purity, and the 72S is a high-purity aluminum-base alloy containing 1 per cent zinc. Both of these materials are relatively weak at room temperature as well as at elevated temperatures. The objective of the present work was the development of aluminum-base alloys which had higher load-carrying capacities at all temperatures up to 600 deg F. without an appreciable sacrifice in resistance to corrosion by water at elevated temperatures and also without an appreciable increase in thermal neutron cross-section value. Accordingly, the work was divided into two phases. The first dealt with the development of alloys having better load-carrying capacity, and the second was concerned with the effects of temperature on the corrosion resistance of the experimental and some commercial alloys in water. The first phase is described in Section I of the report, and the second in Section II of the report.
