Available in PDF, EPUB and Kindle. Book excerpt: Nanostructured aluminum alloys are advantageous for their high strength properties and low density due to the presence of not only multiple material components, but also the presence of nanocrystalline grains that increase strength through grain boundary strengthening. Microstructural analysis is a crucial step in understanding alloy mechanical properties. The alloys observed in this research were analyzed through transmission electron microscope (TEM) observation and grain analysis to determine the average grain size of each nanocrystalline alloy and determine the distribution of grain sizes through each alloy. Average grain sizes for the alloys, found through number fraction analysis, ranged from 44nm to 624nm. Each alloy had a distribution of grain sizes, where the alloy contained high concentrations of grains close their respective average grain sizes with lower concentrations of grains further from the average size.
Download or read book Characterization of Microstructure and Mechanical Properties of AL6063 Using FSP Multipass written by Ripandeep Singh and published by Anchor Academic Publishing. This book was released on 2018 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for low weight and high performance structural materials has revolutionized the technology and has led to the emergence of new processes and methodologies. Friction stir processing (FSP), based on the principle of friction stir welding, is an emerging solid state metal working process. This technique causes intense plastic deformation and high strain rates in the processed material, resulting in precise control of the microstructure through material mixing and densification. FSP process has been successfully used for achieving significant grain refinement and enhancement of surface properties. The present work focuses on the study of behavior of Aluminium cast alloy (Al-6063) processed by the friction stir processing technique. Samples of FSP-ed aluminium were examined and their microstructures, microhardness, Rockwell hardnesss and impact strength were studied and compared with base metal Al-6063. Hardness tester was employed to evaluate the interfacial bonding between the particles and matrix by indenting the hardness with the constant load and constant time. Impact test was employed to know the Impact Strength of samples against the Impact of Hammer.
Download or read book Hot Deformation and Processing of Aluminum Alloys written by Hugh J. McQueen and published by CRC Press. This book was released on 2011-09-28 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive treatise on the hot working of aluminum and its alloys, Hot Deformation and Processing of Aluminum Alloys details the possible microstructural developments that can occur with hot deformation of various alloys, as well as the kind of mechanical properties that can be anticipated. The authors take great care to explain and differentiate hot working in the context of other elevated temperature phenomena, such as creep, superplasticity, cold working, and annealing. They also pay particular attention to the fundamental mechanisms of aluminum plasticity at hot working temperatures. Using extensive analysis derived from polarized light optical microscopy (POM), transmission electron microscopy (TEM), x-ray diffraction (XRD) scanning electron-microscopy with electron backscatter imaging (SEM-EBSD), and orientation imaging microscopy (OIM), the authors examine those microstructures that evolve in torsion, compression, extrusion, and rolling. Further microstructural analysis leads to detailed explanations of dynamic recovery (DRV), static recovery (SRV), discontinuous dynamic recrystallization (dDRX), discontinuous static recrystallization (dSRX), grain defining dynamic recovery (gDRV) (formerly geometric dynamic recrystallization, or gDRX), and continuous dynamic recrystallization involving both a single phase (cDRX/1-phase) and multiple phases (cDRX/2-phase). A companion to other works that focus on modeling, manufacturing involving plastic and superplastic deformation, and control of texture and phase transformations, this book provides thorough explanations of microstructural development to lay the foundation for further study of the mechanisms of thermomechanical processes and their application.
Download or read book Characterization of High Speed Friction Stir Weld Between Dissimilar Aluminum Alloys written by Jingyi Zhang and published by . This book was released on 2017 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction stir welding (FSW) is a solid-state joining technique that is proven to produce superior joint properties and is particularly helpful in the joining of high-strength aluminum alloys. The historically slower welding speed of FSW (in the range of hundreds of millimeters per minute), among other issues associated with the application of the technique has limited its industrial use to small volume productions. Revolutionary high-speed FSW of aluminum blanks has been developed at Pacific Northwest National Laboratory and satisfactory forming properties were achieved. This work focuses on the characterization of the complex microstructures formed in high-speed FSW butt joints and the correlation between the microstructural features and the mechanical properties of the welds. The effect of increased welding speed was first studied on similar aluminum joints. Materials properties investigated including the tensile strength, fracture toughness, elongation, joint efficiency, microhardness, and corrosion susceptibility. The evolution of the materials properties is found to be related to the welding parameters through the complex physical metallurgy events including materials softening, material mixing and transportation, precipitate reaction, dynamic recrystallization, dynamic recovery, and severe plastic deformation during the friction stir welding process. The formation mechanism was then studied in the joining of dissimilar aluminum alloys AA5182-O and AA6022-T4 with different thicknesses. Local textural analysis and particle analysis aided in the understanding of the material flow patterns and helped in the selection of a fixed location of dissimilar alloys to achieve defect-free joints. The microstructural characterization and analysis methods include transmission electron microscopy, electron diffraction, scanning electron microscopy, optical microscopy, energy-dispersive X-ray spectroscopy, electron backscatter and probability density functions.

Available in PDF, EPUB and Kindle. Book excerpt: The major issue of energy saving and conservation of the environment in the world is being emphasized to us to concentrate on lightweight materials in which aluminium alloys are contributing more in applications in the twenty-first century. Aluminium and its related materials possess lighter weight, considerable strength, more corrosion resistance and ductility. Especially from the past one decade, the use of aluminium alloys is increasing in construction field, transportation industries, packaging purposes, automotive, defence, aircraft and electrical sectors. Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are recyclability and its abundant availability in the world. In general, aluminium and its related materials are being processed via casting, drawing, forging, rolling, extrusion, welding, powder metallurgy process, etc. To improve the physical and mechanical properties, scientists are doing more research and adding some second-phase particles in to it called composites in addition to heat treatment. Therefore, to explore more in this field, the present book has been aimed and focused to bridge all scientists who are working in this field. The main objective of the present book is to focus on aluminium, its alloys and its composites, which include, but are not limited to, the various processing routes and characterization techniques in both macro- and nano-levels.

Book excerpt: PREFACE This book offers readers a fairly comprehensive discussion of the hot working of aluminum and aluminum alloys. It is intended to provide an explanation of the possible microstructural developments that can occur with hot deformation of a variety of alloys and the kind of mechanical properties that can be anticipated. The microstructures that evolve with torsion, compression, extrusion and rolling are presented based on extensive analysis from polarized light optical microscopy (POM), transmission electron microscopy (TEM), x-ray diffraction (XRD) scanning electron-microscopy with electron backscatter imaging (SEM-EBSD) and orientation imaging microscopy (OIM). The microstructural analysis leads to detailed explanations of dynamic recovery (DRV), static recovery (SRV), discontinuous dynamic recrystallization (dDRX), discontinuous static recrystallization (dSRX), grain defining dynamic recovery (gDRV) (formerly geometric dynamic recrystallization gDRX) and continuous dynamic recrystallization involving a single phase (cDRX/1-phase) and multiple phases, (cDRX/2-phase). Hot working is carefully explained in the context of other elevated temperature phenomena, some of which overlap hot working. These include creep, superplasticity, cold working and annealing. Creep plasticity occurs at both warm and hot working temperatures, but is usually associated with lower strain-rates and relatively small strains. On the other hand superplasticity involves high tensile strains at similar temperatures, but lower strain rates than utilized in hot working--
