Download or read book Development Program for Natural Aging Aluminum Casting Alloys written by Dr. Geoffrey K. Sigworth and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of 7xx aluminum casting alloys are based on the ternary Al-Zn-Mg system. These alloys age naturally to high strength at room temperature. A high temperature solution and aging treatment is not required. Consequently, these alloys have the potential to deliver properties nearly equivalent to conventional A356-T6 (Al-Si-Mg) castings, with a significant cost saving. An energy savings is also possible. In spite of these advantages, the 7xx casting alloys are seldom used, primarily because of their reputation for poor castibility. This paper describes the results obtained in a DOE-funded research study of these alloys, which is part of the DOE-OIT ''Cast Metals Industries of the Future'' Program. Suggestions for possible commercial use are also given.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objective of this research was to develop and verify a mathematical model and the necessary material database that allow predicting the physical and material property changes that occur in aluminum casting alloys in response to precipitation-hardening heat treatment. The model accounts for all three steps of the typical precipitation hardening heat treatment; i.e., the solutionizing, quenching, and aging steps; and it allows predicting the local hardness and tensile strength, and the local residual stresses, distortion and dimensional changes that develop in the cast component during each step of the heat treatment process. The model uses commercially available finite element software and an extensive database that was developed specifically for the aluminum alloy under consideration namely A356.2 casting alloy. The database includes the mechanical, physical, and thermal properties of the alloy all as functions of temperature. The model predictions were compared to measurements made on commercial cast components that were heat treated according to standard heat treatment protocols and the model predictions were found to be in good agreement with the measurements.

Available in PDF, EPUB and Kindle. Book excerpt: Casting Aluminum Alloys, Second Edition, the follow up to the fall 2007 work on the structure, properties, thermal resistance, corrosion and fatigue of aluminum alloys in industrial manufacturing, discusses findings from the past decade, including sections on new casting alloys, novel casting technologies, and new methods of alloys design. The book also includes other hot topics, such as the implementation of computational technologies for the calculation of phase equilibria and thermodynamic properties of alloys, the development of software for calculation of diffusion processes in aluminum alloys, computational modeling of solidification microstructure and texture evolution of multi-component aluminum materials. In addition to changes in computational predictive abilities, there is a review of novel casting aluminum alloy compositions and properties, as well as descriptions of new casting technologies and updates to coverage on the mechanical properties of aluminum casting alloys. - Presents a discussion of thermodynamic calculations used for assessing non-equilibrium solidifications of casting aluminum alloys - Expands coverage of mathematical models for alloy mechanical properties, helping facilitate the selection of the best prospective candidate for new alloy development - Contains a new section that describes the self-consistent evaluation of phase equilibria and thermodynamic properties of aluminum alloys

Download or read book Aluminum Alloys Contemporary Research and Applications written by A. K. Vasudevan and published by Elsevier. This book was released on 2012-12-02 with total page 727 pages. 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: Use of acceptable aging treatments on the basis of processing and chemistry permits attainment of near optimum physical properties for aluminum shell castings. Data developed on aging times for one aluminum casting alloy or one casting process are not always applicable to another aluminum casting alloy or process. A wide range of aging times and temperatures will produce near optimum properties for 356 aluminum with less than .30% iron. However, the acceptable aging cycle, time and temperature ranges narrow rapidly for iron contents of over .40%. (Author).
