Available in PDF, EPUB and Kindle. Book excerpt: Ductile materials such as aluminum alloys have been the primary material of choice for structural components of aircraft such as fuselage, wing, etc. because of their light weight, ease of forming and resistance to failure under shock loads. There are two primary types of aluminum alloys used in aircraft: cast alloys and wrought alloys. Majority of the traditionally used cast aluminum alloys in aircraft manufacturing are the Al-Cu or Al-Si-Mg alloys including A214, A355, A356 and E 357. Aluminum castings are typically produced using green sand, permanent mold casting or die casting. However, aluminum castings are susceptible to porosity defects. Porosity is a microscopic void or hole found in a casting. To eliminate micro-porosity defects in aluminum castings, multiple heat treatments can be used. In particular hot isostatic pressing (HIP) can be used to effectively to remove sub-surface porosity in complex shaped castings. HIPing process includes the use of elevated temperature and the application of a hydrostatic pressure via pressurized gas. Previous work has demonstrated that widely used aluminum casting alloys such as A356, A204, A206 have shown considerable improvement in mechanical properties when HIPed. However, no study has been done on aluminum casting alloy E357. The E357 alloy combines excellent casting characteristics with improved strength compared to the widely use A356 alloy. Silicon combines with the magnesium in these alloys to form Mg2Si which strengthens the alloys during final precipitation heat treatments. To understand the effects of hot isostatic pressing on the performance of casting Aluminum E 357 alloy tensile testing and charpy impact testing were carried out on cast E357 test specimens which were divided into three groups- HIPed and T6 heat treated specimens,Homogenized and T6 heat treated specimens and Non HIPed and T6 heat treated specimens. Samples were evaluated to understand the effects of processing cycles on the resultant mechanical properties and microstructure with respect to microporosity and size of silicon particles. This study was conducted as an effort to characterize impact of Hot Isostaic Pressing on aluminum E357 casting for Sikorsky Aircraft Corporation. It was observed that, HIPing process helped in reducing %porosity by 37.83% and increased size of silicon particle has by 18.08%. Significant increase in %elongation was also observed in HIPed samples as compared to non HIPed samples. Overall HIPing process and subsequent heat treatment helps to improve % elongation significantly although the improvements in ultimate tensile strength and yield strength is not significant. Microstructure analysis reveals that HIPing results in a noticeable reduction in % porosity which tends to increase mechanical properties and reduce property variation.
Download or read book Material Flow and Microstructural Evolution During the Extrusion written by Yahya Mahmoodkhani and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central to the competitiveness of Rio Tinto Alcan and other aluminum manufacturers, is the quantitative linkage between products and the processes by which they are made. This type of activity has gained attention internationally and there are significant programs underway to develop through process models for various metallurgical fabrication processes. Inherently, the need for these types of models is that the properties of the metal products depend on the microstructure of the material which in turn is a complex function of composition, grain size and orientation, distribution of phases and precipitates and its thermo-mechanical history. The development of a particular microstructure and the desired properties in an industrial process however is less than straightforward because the latter usually involves a complex deformation and temperature path which can be very different through the thickness of the material depending on its location. This book describes the development of a mathematical model and experimental study for the material flow and microstructure changes during extrusion of AA3003 aluminum alloy which is used for manufacturing of automobile heat exchangers.

Download or read book Microstructural Evolution in the 2219 Aluminum Alloy During Severe Plastic Deformation written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous investigations have demonstrated that intense plastic deformation is an attractive procedure for producing an ultrafine grain size in metallic materials. Torsional deformation under high pressure and equal-channel angular extrusion are two techniques that can produce microstructures with grain sizes in the submicrometer and nanometer range. Materials with these microstructures have many attractive properties. The microstructures formed by these two processing techniques are essentially the same and thus the processes occurring during deformation should be the same. Most previous studies have examined the final microstructures produced as a result of severe plastic deformation and the resulting properties. Only a limited number of studies have examined the evolution of microstructure. As a result, some important aspects of ultra-fine grain formation during severe plastic deformation remain unknown. There is also limited data on the influence of the initial state of the material on the microstructural evolution and mechanisms of ultra-fine grain formation. This limited knowledge base makes optimization of processing routes difficult and retards commercial application of these techniques. The objective of the present work is to examine the microstructure evolution during severe plastic deformation of a 2219 aluminum alloy. Specific attention is given to the mechanism of ultrafine grain formation as a result of severe plastic deformation.

Available in PDF, EPUB and Kindle. Book excerpt: For all kinds of materials, phase transformations show common phenomena and mechanisms, and often turn a material, for example metals, multiphase alloys, ceramics or composites, into its technological useful form. The physics and thermodynamics of a transformation from the solid to liquid state or from one crystal form to another are therefore essential for creating high-performance materials. This handbook covers phase transformations, a general phenomenon central to understanding the behavior of materials and for creating high-performance materials. It will be an essential reference for all materials scientists, physicists and engineers involved in the research and development of new high performance materials. It is the revised and enhanced edition of the renowned book edited by the late P. Haasen in 1990 (Vol. 5, Materials Science and Technology).
