This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study comprehensively analyzed the mechanical behavior and microstructural evolution of aluminum alloy AA2219-T87 undergoing high deformation and strain rates at elevated temperature via hot torsion tests. An integrated experimental and modeling approach has been employed, where a finite element model is developed with ABAQUS to address local deformation and non-uniform temperature distribution along the specimen gauge section. A Johnson-Cook constitutive material model is calibrated based on the calculated and measured torque curves at different conditions. Combined with the ABAQUS calculated local thermo-mechanical conditions, microstructure modeling using established literature-based equations are established to provide insights into grain size distribution and recrystallization mechanisms. The calibrated material constitutive model, recrystallization model, and grain size model can be utilized to model various manufacturing processes which involves hot deformation of aluminum alloys in the intermediate strain rate range of 14/s-78/s. These findings were applied to further works with Bobbin Tool Friction Stir Welding of thick plate AA2219. Analysis of cross sections and welding parameter effects on microstructural and phenomenological outcomes were performed to maximize understanding of the specific material behavior in elevated temperature, high strain rate processes as seen in hot torsion as well as friction based solid state welding.

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 Optimizing Mechanical Properties and Thermal Stability of Age Hardenable Aluminum Alloys Through Theoretical Modeling Alloy Modification and Thermal Mechanical Properties written by and published by . This book was released on 2003 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research was concerned with a practical approach to the design of an improved age-hardenable aluminum alloy for moderate temperature application. The process involved extensive empirical research, theoretical simulation and modeling, calculated phase diagrams and first principle calculations and analytical techniques. Microstructure characterization and analytical transmission electron microscopy were employed to refine the development of the quaternary Al-Cu-Mg-Ag phase diagram Differential scanning calorimetry and electron diffraction were implemented to investigate the microstructural evolution of the ternary alloys and to validate calculated equilibrium phase boundaries. Energy dispersive spectroscopy was also used to illustrate the effect of trace additions on the phase boundaries that are important for the thermal stability of this class of alloys. Computer simulation & modeling were used to identify the microstructure that will result in the optimal combination of mechanical properties. Unavailable parameters were calculated from first principle atomistic modeling. The major objective of this research program has been to illustrate the use of modeling and simulation in alloy design and therefore aid in the early insertion of new high performance materials.
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 Mixed mode Model for Studying Microstructural Evolution of Precipitates Inside Aluminum Alloys written by Tohid Naseri and published by . This book was released on 2020 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum is one of the most used non-ferrous metal in the world with an enormous range of applications from simple kitchenware to advanced spacecraft. In applications where high mechanical properties are needed, like in the car industry, it is strongly required to improve the mechanical properties. As the final distribution of precipitates plays a crucial role in mechanical properties of these alloys, a better understanding of the microstructural evolution and kinetics of precipitation can help noticeably the design of the heat treatment process of aluminum alloys. However, due to the size and morphology of the precipitates, experimental studies of the precipitation required advanced characterization methods like transmission electron microscopy which is not an industrially favorable technique since it is costly and required a lot of technical expertise. Numerical investigation can be a desirable tool to model the evolution of the precipitates and the corresponding mechanical properties. This study presents a kinetic model of precipitation. Unlike many studies that mainly focus on the diffusion and surface energy, we consider interfacial mobility as an effective variable in a mixed-mode model. This variable not only provides us the possibility to study the precipitates’ evolution in multicomponent alloys but also can boost the calculation performance. Moreover, the other superiority of this model is the possibility of working with complex multiphase industrial Al alloys by considering the growth and the dissolution of different types of precipitates simultaneously.
