Available in PDF, EPUB and Kindle. Book excerpt: In recent years, Electron Beam Melting (EBM) has matured as a technology for additive manufacturing of dense metal parts. The parts are built by additive consolidation of thin layers of metal powder using an electron beam. With EBM, it is possible to create parts with geometries too complex to be fabricated by other methods, e.g. fine network structures and internal cavities. The process is run in vacuum, which makes it well suited for materials with a high affinity to oxygen, i.e. . titanium compounds. We present material data from a recently conducted study of how melt strategy affects EBM process for gamma titanium aluminide, Ti-48Al-2Cr-2Nb. The investigation includes microstructural characterization, grain size measurement and tensile testing.

Download or read book Additive Manufacturing of Titanium Alloys written by Bhaskar Dutta and published by Butterworth-Heinemann. This book was released on 2016-06-17 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive Manufacturing of Titanium Alloys: State of the Art, Challenges and Opportunities provides alternative methods to the conventional approach for the fabrication of the majority of titanium components produced via the cast and wrought technique, a process which involves a considerable amount of expensive machining. In contrast, the Additive Manufacturing (AM) approach allows very close to final part configuration to be directly fabricated minimizing machining cost, while achieving mechanical properties at least at cast and wrought levels. In addition, the book offers the benefit of significant savings through better material utilization for parts with high buy-to-fly ratios (ratio of initial stock mass to final part mass before and after manufacturing). As titanium additive manufacturing has attracted considerable attention from both academicians and technologists, and has already led to many applications in aerospace and terrestrial systems, as well as in the medical industry, this book explores the unique shape making capabilities and attractive mechanical properties which make titanium an ideal material for the additive manufacturing industry. Includes coverage of the fundamentals of microstructural evolution in titanium alloys Introduces readers to the various Additive Manufacturing Technologies, such as Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) Looks at the future of Titanium Additive Manufacturing Provides a complete review of the science, technology, and applications of Titanium Additive Manufacturing (AM)
Download or read book Thermo Mechanical Modeling of Additive Manufacturing written by Michael Gouge and published by Butterworth-Heinemann. This book was released on 2017-08-03 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermo-mechanical Modeling of Additive Manufacturing provides the background, methodology and description of modeling techniques to enable the reader to perform their own accurate and reliable simulations of any additive process. Part I provides an in depth introduction to the fundamentals of additive manufacturing modeling, a description of adaptive mesh strategies, a thorough description of thermal losses and a discussion of residual stress and distortion. Part II applies the engineering fundamentals to direct energy deposition processes including laser cladding, LENS builds, large electron beam parts and an exploration of residual stress and deformation mitigation strategies. Part III concerns the thermo-mechanical modeling of powder bed processes with a description of the heat input model, classical thermo-mechanical modeling, and part scale modeling. The book serves as an essential reference for engineers and technicians in both industry and academia, performing both research and full-scale production. Additive manufacturing processes are revolutionizing production throughout industry. These technologies enable the cost-effective manufacture of small lot parts, rapid repair of damaged components and construction of previously impossible-to-produce geometries. However, the large thermal gradients inherent in these processes incur large residual stresses and mechanical distortion, which can push the finished component out of engineering tolerance. Costly trial-and-error methods are commonly used for failure mitigation. Finite element modeling provides a compelling alternative, allowing for the prediction of residual stresses and distortion, and thus a tool to investigate methods of failure mitigation prior to building. Provides understanding of important components in the finite element modeling of additive manufacturing processes necessary to obtain accurate results Offers a deeper understanding of how the thermal gradients inherent in additive manufacturing induce distortion and residual stresses, and how to mitigate these undesirable phenomena Includes a set of strategies for the modeler to improve computational efficiency when simulating various additive manufacturing processes Serves as an essential reference for engineers and technicians in both industry and academia
Download or read book Build Orientation Part Size Geometry and Scan Path Influence on the Microstructure and Fatigue Life of Ti 6Al 4V Fabricated by Electron Beam Melting written by Andrew Harrison Chern and published by . This book was released on 2018 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron beam melting (EBM), a powder bed fusion process, is a rapidly-developing metal additive manufacturing method that allows for fabrication of complex geometries directly from a computer file that would be difficult or impossible to fabricate by traditional methods. EBM holds significant interest in the aerospace industry for the high-strength titanium alloy, Ti-6Al-4V, because of its promising opportunity to reduce buy-to-fly ratios. However, a fundamental understanding of the fatigue-damage tolerance, underlying mechanisms, and impact of processing conditions is required for use of EBM fabrication of critical flight components. To investigate how the EBM process affects components, different parameters were varied and the resulting microstructure and mechanical properties were characterized using 4-point bend fatigue tests, tensile tests, Vickers microhardness indentations, scanning electron microscopy, and optical microscopy. The orientation, scan path, and surface finish were varied and the effects on microstructure, tensile properties, and fatigue behavior are reported and discussed. As expected, the surface roughness left by the EBM fabrication adversely impacts the fatigue behavior and sufficient machining is required to remove all surface roughness effects. It was discovered that the build orientation affects the tensile ductility and fatigue life, but the strength and hardness are largely independent of orientation. The EBM Ti-6Al-4V shows similar fatigue life to conventional material, but is limited by porosity defects. The altered processing parameters affected the fatigue behavior, but promising results indicate that EBM can be a viable manufacturing method for flight critical components.
