Available in PDF, EPUB and Kindle. Book excerpt: This atlas provides an in-depth understanding of the metallurgy and fracture behavior of aluminum-silicon casting alloys, which are used in a wide variety of automotive, aerospace, and consumer product applications. The atlas includes over 300 high-definition microfractographs of fracture profiles and fracture surfaces, accompanied with detailed descriptions and analysis of the fracture features and their significance in the selection, processing, properties, and performance of the alloy. The microfractographs are described and classified according to criteria described in detail in the introductory chapters in the book. The factors determining the fracture mechanism in these alloys, on the basis of their physical and mechanical properties and fracture mechanics, are described and analyzed. The set of micrographs in this atlas include several unique features: classification according to the alloy and its processing history, detailed analysis of selected microregions of the fracture surface, reference of the fracture features to the phase constituents of the alloy, and high resolution and high microscopic magnification of the SEM images. This book will be of great value to anyone involved in the selection, processing, application, testing, or evaluation of aluminum-silicon castings. The target audience includes metallurgists, foundry personnel, failure analysts, purchasers of castings, researchers in physical and mechanical metallurgy, students, and educators.

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.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2D and 3D characterization and image analysis have been performed to measure the microstructural changes associated with: different Sr, Fe and Mn levels, the casting process (Gravity Die Casting vs. Lost Foam Casting, LFC) and the solution heat treatments in A319 alloy. The evolution of microstructure in Al-Si-Cu alloy with different alloying elements addition was also studied by thermal analysis. The microstructure consists of hard inclusions, i.e. eutectic Si, iron-intermetallics and Al2Cu phases, and pores. The effect on mechanical properties of the alloys has been monitored by Vickers hardness measurement and tensile tests. Surface damage observations are performed on A319 alloys with different Fe content during in-situ tensile test, which allows following the development and localization of the deformation and cracks. Digital image correlation measurement and fractography highlighted the role of iron-intermetallics in the cracks initiation and propagation. Tensile tests on LFC A319 samples with two different heat treatment conditions were performed in-situ under Laboratory Computed Tomography. Strain measurements from digital volume correlation and observed damage mechanisms show that cracks initiate at hard inclusions in the areas with sufficient stress concentrations, which are mainly provided by large pores, and often propagate through the fracture of Al2Cu, iron-intermetallics, as well as through Si particles rather than by their decohesion from the matrix.
Download or read book Performance of Aluminum Silicon Cast Alloys written by Adel Mohamed and published by LAP Lambert Academic Publishing. This book was released on 2010-12 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuing quest for aluminum castings with enhanced mechanical properties for applications in the automotive industries has intensified the interest in Al Si alloys. However, the commercial application of these materials depends on the control of the structure of the shape and distribution of the eutectic silicon particles in the matrix, as also by the intermetallics phases that occur upon solidification. Thus, the book was designed with the aim of understanding how alloying elements, trace elements, and heat treatment influence changes in the microstructure and, consequently, the performance of hypoeutectic and near-eutectic Al-Si alloys. Microstructural examination was carried out using optical microscopy, image analysis, and electron probe microanalysis (EPMA), wavelength dispersive spectroscopic (WDS) analysis facilities. By examining the mechanical properties of Al-Si alloys in conjunction with microstructure this book provides a valuable description of the development and behaviour of these materials
Download or read book Effect of Composition in As Cast and Homogenized Al Si Cu Alloys written by Ashrafi Ehsan Ahmed and published by LAP Lambert Academic Publishing. This book was released on 2014-08-04 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminium alloys with a wide range of properties are used in engineering structures. These properties can be largely modified by changing the alloy composition and by cold working. Si, Cu, Zn and Mg are the most commonly used alloying elements in aluminium, which have sufficient solid solubility. The as-cast microstructure of cast aluminium alloys normally displays significant segregation and supersaturation. For this, homogenization of aluminium alloys is often done to improve workability and mechanical properties. This book is based on the research about influence of Cu content, cold working and homogenization in Al-Si alloys. The effects were analysed using microstructure study, phase-property modelling, image analysis and hardness measurement. This work should help researchers and metallurgists who are working on modification of alloy properties. Also it will help students who have keen interest in study of microstructure, modelling and image analysis.

Download or read book Microstructural Development in Al Si Powder During Rapid Solidification written by Amber Lynn Genau and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Powder metallurgy has become an increasingly important form of metal processing because of its ability to produce materials with superior mechanical properties. These properties are due in part to the unique and often desirable microstructures which arise as a result of the extreme levels of undercooling achieved, especially in the finest size powder, and the subsequent rapid solidification which occurs. A better understanding of the fundamental processes of nucleation and growth is required to further exploit the potential of rapid solidification processing. Aluminum-silicon, one alloy of significant industrial importance, was chosen as a model for simple eutectic systems displaying an unfaceted/faceted interface and skewed coupled eutectic growth zone. Al-Si powder produced by high pressure gas atomization was studied to determine the relationship between microstructure and alloy composition as a function of powder size and atomization gas. Critical experimental measurements of hypereutectic (Si-rich) compositions were used to determine undercooling and interface velocity, based on the theoretical models which are available. A revised microstructural map is proposed which allows the prediction of particle morphology based on temperature and composition.
