This book was released on 2015-12-24 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the latest efforts to develop aluminum nanocomposites with enhanced damping and mechanical properties and good workability. The nanocomposites exhibited high strength, improved damping behavior and good ductility, making them suitable for use as wires. Since the production of metal matrix nanocomposites by conventional melting processes is considered extremely problematic (because of the poor wettability of the nanoparticles), different powder metallurgy routes were investigated, including high-energy ball milling and unconventional compaction methods. Special attention was paid to the structural characterization at the micro- and nanoscale, as uniform nanoparticle dispersion in metal matrix is of prime importance. The aluminum nanocomposites displayed an ultrafine microstructure reinforced with alumina nanoparticles produced in situ or added ex situ. The physical, mechanical and functional characteristics of the materials produced were evaluated using different mechanical tests and microstructure investigation techniques. The book presents and discusses the experimental results in detail, and offers suggestions for future research directions.

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.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a thorough study of the microstructure evolution of alloys and welds subjected to different processing conditions. The microstructure of alloys and welds are strongly influenced by processing conditions which influences the materials mechanical properties and performance. A new technique has been developed to quantify the spatial variation of grain sizes, grain shapes, and grain boundary curvatures in the fusion zone (FZ) and heat affected zone (HAZ) of welds. Very limited past work has been done to quantify many of these grain microstructure properties characterized from this technique. Trends between each microstructural feature has been captured between welds subjected to different welding parameters and post weld processing. Accruing knowledge of the microstructural trends with processing conditions has proven to be advantageous in developing correlations with various mechanical properties and advancing weld engineering. The microstructure evolution of gas tungsten arc molybdenum welds subjected to multiple weld processing conditions has been evaluated with the developed technique. Varying the heat input, welding speed, and welding technique caused noticeable to drastic changes in the FZ and HAZ grain microstructure which also influenced the materials mechanical properties. The microstructure evolution of DOP-26 GTA welds subjected to different levels of thermal exposures has also been evaluated with the developed technique. Iridium alloys are primary used in space applications and the thermal exposures simulated typical operation conditions and launch failure scenarios. Annealing causes significant changes to many grain properties in the FZ of these welds which was correlated to changes in mechanical properties. Other techniques including SEM and EBSD has been done to capture the precipitate distribution and grain texture in the weld answering questions posed from the microstructure evaluation results. Alloy design and development is critical for the new generation of iridium alloys typically used for space applications. Currently Iridium is made into DOP-26 alloyed with 0.3 wt% tungsten, 50 ppt aluminum, and 60 parts per million (ppm) thorium. The thorium actively enhances the grain boundary strength and hinders grain growth during high thermal exposures with the formation eutectic primary precipitates. There is a desire to replace thorium with cerium, a non-radioactive potentially less expensive alloying substitute with thorium which behaves like thorium in iridium. A recrystallization study with respect to cerium and thorium content in iridium alloys has been evaluated. The recrystallization behavior of a material is influenced by the nature and quantity of the alloying element which governs the final microstructure post processing. The microstructure evolution at different stages of recrystallization was evaluated by capturing the percentage recrystallized, texture, and strain. The change in recrystallization rates at various annealing temperatures with respect to cerium content has been determined from the results. Analyzing the texture provided insight to how substituting cerium influences the microstructure by means of the formation and strength (sharpness) of cubic texture and fiber textures with annealing temperature. An understanding of the recrystallization behavior with respect to alloying is critical in developing processing steps to produce desirable microstructures with the best mechanical properties.

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.
