Download or read book Equal Channel Angular Extrusion Characteristics on Mechanical Behavior of Aluminum Alloy written by Abiodun Ayodeji Abioye and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials strengthened by conventional methods such as strain hardening, solute additions, precipitation and grain size refinement are often adopted in industrial processes. But there is limitation to the amount of deformation that these conventional methods can impact to a material. This study focused on the review of major mechanical properties of aluminum alloys in the presence of an ultrafine grain size into polycrystalline materials by subjecting the metal to an intense plastic straining through simple shear without any corresponding change in the cross-sectional dimensions of the sample. The effect of the heavy strain rate on the microstructure of aluminum alloys was in refinement of the coarse grains into ultrafine grain size by introducing a high density of dislocations and subsequently re-arranging the dislocations to form an array of grain boundaries. Hence, this investigation is aimed at gathering contributions on the influence of equal channel angular extrusion toward improving the mechanical properties of the aluminum alloys through intense plastic strain.

Download or read book Influence of the Precipitation state on the Thermal Stability of Severely Deformed Aluminum Alloys written by Rolf Berghammer and published by Cuvillier Verlag. This book was released on 2014-10-29 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: A promising way to increase the strength of aluminum alloys is by grain refinement. Therefore the production of so-called ultra-fine grained (UFG) microstructures by severe plastic deformation (SPD) is a very interesting topic. One of the most common SPD processes is Equal Channel Angular Pressing (ECAP), which was compared to Confined Channel Die Pressing (CCDP) and cold rolling.In the focus of this work lays on the one hand the influence of different precipitation states on the formation of UFG structures and their influence on the mechanical properties and on the other hand it was examined if the thermal stability of these structures can be improved either by supersaturated solid solution(by impurity drag) or by precipitates (by grain boundary pinning).With a better understanding of the ongoing softening mechanisms a good combination of high strength and good ductility can be achievedby alternating SPD and heat treatment.

Book excerpt: Additive and Traditionally Manufactured Components: A Comparative Analysis of Mechanical Properties looks at the mechanical properties of materials produced by additive manufacturing (AM) and compares them with conventional methods. Since the production of objects by AM techniques can used in a broad array of materials, the alloys presented are the ones most commonly produced by AM - Al alloys, Ti alloys and steel. The book explores the six main types of techniques: Fused Deposition Method (FDM), Powder Bed Fusion (PBF), Inkjet Printing, Stereolithography (SLA), Direct Energy Deposition (DED) and Laminated Object Manufacturing (LOM), and follows with the techniques being utilized for fabrication. Testing of AM fabricated specimens, including tension, compression and hardness is included, along with a comparison of those results to specimens obtained by conventional fabrication methods. Topics covered include static deformation, time dependent deformation (creep), cyclic deformation (fatigue) and fracture in specimens. The book concludes with a review of the mechanical properties of nanoscale specimens obtained by AM. Thoroughly explores AM processes that can be utilized for experimental design Includes a review of dislocations observed in specimens obtained by AM Compares the impact of both additive and traditional manufacturing techniques on the mechanical properties of 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.
