This book was released on 2000 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced manufacturing processes such as near-net-shape forming can reduce production costs and increase the reliability of launch vehicle and airframe structural components through the reduction of material scrap and part count and the minimization of joints. The current research is an investigation of the processing-microstruture-property relationships for shear formed cylinders of the Al-Cu-Li-Mg-Ag alloy 2195 for space applications and the Al-Cu-Mg-Ag alloy C415 for airframe applications. Cylinders which had undergone various amounts of shear-forming strain were studied to correlate the grain structure, texture, and mechanical properties developed during and after shear forming.

Book Semi Solid Processing of Alloys and Composites

Download or read book Semi Solid Processing of Alloys and Composites written by Shahrooz Nafisi and published by MDPI. This book was released on 2020-06-18 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semi-solid metal (SSM) processing, as a viable alternative manufacturing route to those of conventional casting and forging, has not yet been fully exploited despite nearly half a century since its introduction to the metal industry. The slow pace of adopting SSM routes may be due to various reasons, including capital costs, profit margins, and, most importantly, the lack of detailed analysis of various SSM processes in open literature to confidently establish their advantages over more conventional routes. Therefore, the SSM community must disseminate their findings more effectively to generate increased confidence in SSM processes in the eyes of our industrial leaders. As such, we have embarked on the task to invite the leaders in SSM research to share their findings in a Special Issue dedicated to semi-solid processing of metals and composites. SSM processing takes advantage of both forming and shaping characteristics usually employed for liquid and solid materials. In the absence of shear forces, the semi-solid metal has similar characteristics to solids, i.e., easily transferred and shaped; by applying a defined force, the viscosity is reduced and the material flows like a liquid. These unique dual characteristics have made SSM routes attractive alternatives to conventional casting on an industrial scale. With the intention of taking full advantage of SSM characteristics, it is crucial to understand SSM processing, including topics such as solidification and structural evolution, flow behavior through modelling and rheology, new processes and process control, alloy development, and properties in general. This Special Issue focuses on the recent research and findings in the field with the aim of filling the gap between industry and academia, and to shed light on some of the fundamentals of science and technology of semi-solid processing.

Book Structure property process Relations of Solid state Additively Manufactured Aerospace Aluminum Alloys

Download or read book Structure property process Relations of Solid state Additively Manufactured Aerospace Aluminum Alloys written by Craig Joseph Taylor Mason and published by . This book was released on 2020 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing processes provide new avenues to additively repair or manufacture complex aerospace components. There has been limited success in additively manufacturing aluminum alloys and aluminum metal matrix composites that are susceptible to hot-cracking. Recently, the development of a transformative solid-state additive manufacturing process, Additive Friction Stir-Deposition (AFS-D), incorporated the benefits of additive manufacturing and severe plastic deformation processes that provided a new path to fabricate fully-dense aluminum alloy and aluminum metal matrix composite structures. In this work, the microstructural evolution and mechanical response of an Al-Cu-Mg metal matrix composite (MMC) containing 20 weight percent Al2O3 and an AA7050 isogrid structure was additively manufactured through the AFS-D process. Microstructural characterization of the tempered and overaged Al-MMC employed optical microscopy, Scanning Electron Microscopy, and Electron Backscatter Diffraction. Additionally, to quantify the mechanical response of the tempered and overaged Al-MMC, quasi-static tensile experiments were conducted in the longitudinal and transverse orientation. Dynamic tensile testing was performed on the tempered and overaged AFS-D Al-Cu-Mg material in the transverse orientation using a Split-Hopkinson pressure bar. The resulting microstructural and mechanical analysis was captured via the internal state variable (ISV) plasticity damage model. The model is consistent with continuum level kinematics, kinetics, and thermodynamics. The following research provides a foundation for rapidly additively manufacture large MMC structures through AFS-D. This study produced a fully dense AA7050 isogrid structure was manufactured without the need for additional alloying elements. Three sections of the component that exhibit differing thermomechanical processing history were evaluated for the resulting microstructure and mechanical response. The microstructural characterization of the as-deposited AA7050 employed TEM, SEM, and EBSD. The as-deposited AA7050 exhibited a refinement of the constituent particles and grains within the microstructure. Additionally, to quantify the mechanical response of the as-deposited AA7050, quasi-static tensile and high rate tensile experiments were conducted. The Internal-State Variable Plasticity model was successfully modified to be able to capture material anisotropy as a function of precipitate free zones and secondary phases size within the grain.

Book Optimizing the Heat Treatment of High Strength Al Si Mg and Al Cu Mg Zn

Download or read book Optimizing the Heat Treatment of High Strength Al Si Mg and Al Cu Mg Zn written by Ibrahim Mohamed Fawzy and published by LAP Lambert Academic Publishing. This book was released on 2015-10-30 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of aeronautical alloys requires the use of these particular alloys for their strength and ductility. These properties can be further enhanced by controlling the added alloying elements as well as the heat treatment parameters. The objective of the present work was to determine the effect of the interactions between element additions and heat treatment on the alloy microstructure and mechanical properties. The present study was carried out to investigate both the formability and mechanical properties of 6xxx alloy series. The slabs (7 x 11 x 1.5 cm each) were machined and homogenized for 10 h at 520 C, followed by air cooling. The results show that a -iron phase displays low formability and hinders deformation of the grains during cold rolling and leads to premature cracking. The cold rolled structure contains elongated grains with broken -Al5FeSi platelet fragments. In the Mn-containing alloy, the -iron phase is more easily deformable while addition of Sr does not improve the alloy behavior. With beryllium additions, the iron intermetallics precipitate in the form of small, globular -Al8Fe2SiBe script particles, in the interdendritic regions."
