This book was released on 1988 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research performed during this program demonstrated that the metastable microstructures upon which rapidly-solidified, powder metallurgy (RS/PM) aluminum alloys depend for their unique mechanical properties can be both 'recreated' using rapid solidification fusion welding processes and/or 'retained' using solid-state welding processes. Alloys investigated included Al-Fe-X dispersoid-type compositions developed for superior elevated-temperature properties and Al-Li-X alloys developed for high strength and modulus and low density. Processes found to be most effective for the joining of these alloys included rapid-solidification electron beam and capacitor-discharge welding and solid-state inertia-friction and diffusion welding. Metallurgical phenomena investigated included solidification, solid-state phase transformations, defect formation and structure-property-fracture relationships. RS/PM aluminum alloys which contain low hydrogen levels, such as the inertly produced Al-8Fe-2Mo alloy, were effectively joined using the high-energy density electron-beam welding. Keywords: Iron, Lithium, Molybdenum, Cerium.

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.

Download or read book Application of Rapid Solidification Techniques to Aluminum Alloys written by C. G. Lebi and published by . This book was released on 1978 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This portion of the program was conducted for the purpose of developing a predictive model of heat flow and solidification for aluminum alloys produced under the high cooling rate conditions achievable in atomization processes. It is a combined experimental and theoretical study of the relationship between the important solidification variables (e.g. cooling rate, temperature gradients, interface shape and velocity, supercooling and transformation kinetics) and the structure of rapidly solidified aluminum alloy powders. This report covers that portion of the investigations which addressed the characterization of the thermal history of rapid solidification in metal droplets, and its effects on powder microstructure. The main effort was focused on modelling the heat flow during solidification, and relationships were established between the atomization parameters, the growth kinetics, the interface velocity and undercooling, and other important variables. Numerical solutions based on the enthalpy model were developed, and their results compared to the trends predicted from the Newtonian model. The analysis covered situations of isothermal solidification at the melting temperature, as well as those where significant undercoolings are necessary for nucleation and growth. The implications of single vs. multiple nucleation were also discussed. The concepts developed from the heat flow analysis were coupled to microstructural observations in Aluminum alloy powders, mostly in the submicron size range. It was shown that reducing the particle size decreases the extent of segregation, promotes multiple nucleation and the formation of twins during solidification.

Lewis and published by . This book was released on 1978 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the feasibility of developing aluminum alloys from rapidly solidified powders having significant improvements in properties for aerospace structural applications. This study was comprised of four tasks: (1) survey of current technology for rapid solidification of aluminum alloy powders, (2) metallurgical and property evaluation of unusual composition aluminum alloys having some promise for advanced structural applications, (3) a series of design tradeoff studies of selected space, missile, and aircraft structures to assess the effect of assumed property improvements on weight savings and, where possible, performance, and (4) formulation of a plan to exploit advanced aluminum alloys for application to new weapons systems where significant improvements in systems effectiveness would result.

Download or read book Advanced Aluminum Alloys from Rapidly Solidified Powders written by R. E. Lewis and published by . This book was released on 1979 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced aluminum alloys are to be developed that will provide major payoffs for important new aircraft, spacecraft, and missile systems in the next decade. Payoffs will result from weight savings of structural components which, in turn, lead to increased range, payload, service life, and decreased life-cycle cost. The objective of this program is to develop advanced aluminum alloys from rapidly solidified particulate that meet specific property goals. In addition, the program is to establish a metallurgical basis suitable for manufacturing scale-up and application to new weapon systems.

Available in PDF, EPUB and Kindle. Book excerpt: The influence of metallurgical and process variables on the consolidation, densification, and properties of rapidly solidified aluminum alloy powders was investigated. Cold compaction, hot pressing, powder extrusion, and explosive consolidation were used to consolidate rapidly solidified 99.9% aluminum powder. The alloys included in the study provide wide variations in hardness, flow stress, work hardening rate, plasticity, and oxide-film thickness. The consolidation techniques for the study provide variations in pressure, compaction rate, and extent of oxide film breakdown. Three 35-kg lots of rapidly solidified 99.9% A1 and aluminum alloy powders were prepared by vacuum atomization, and the powders were characterized with respect to particle size distribution, cooling rates, constituent phases, and volatile contaminants. The pressure dependence of densification during cold compaction was correlated with the yield stress and work hardening of the alloys.
