Additive Friction Stir Deposition

Additive Friction Stir Deposition is a comprehensive summary of the state-of-the-art understanding on this emerging solid-state additive manufacturing technology. Sections cover additive friction stir deposition, encompassing advances in processing science, metallurgical science and innovative applications. The book presents a clear description of underlying physical phenomena, shows how the process determines the printing quality, covers resultant microstructure and properties in the as-printed state, highlights its key capabilities and limitations, and explores niche applications in repair, cladding and multi-material 3D printing.

Serving as an educational and research guide, this book aims to provide a holistic picture of additive friction stir deposition-based solid-state additive manufacturing as well as a thorough comparison to conventional beam-based metal additive manufacturing, such as powder bed fusion and directed energy deposition.

"Prof. Hang Yu has created a masterpiece in this first book on the additive friction stir deposition technology. Additive friction stir deposition is emerging as a very high deposit rate additive manufacturing process and has started finding real world applications. This book provides a timely overview of this new field. As researchers and practitioners of this new technology work on various new opportunities, they will benefit from the necessary theoretical basis provided in Chapters 2, 3, 4 and 7. Prof. Yu draws from his own research and experience to provide insights. It is a very comprehensive book that covers from process physics and materials science to tooling/applications. This is a great resource for students who get in this field and is a "must read"book. Faculty teaching advanced manufacturing processes can use several chapters to teach about this disruptive manufacturing process."—Dr. Rajiv Mishra, University Distinguished Professor, University of North Texas, USA

"A very timely book on this new emerging solid-state additive manufacturing technology. An excellent reference for those who are interested in 　this dynamic and fast growth topic, from fundamentals of the process, technology innovations, and resulting microstructure and properties."—Dr. Zhili Feng, Distinguished R&D Staff, and Leader Materials Joining Group, Oak Ridge National Laboratory, USA

"Prof. Yu’s research has placed him and his team at the forefront of a technology that is seeing tremendous growth on the global additive manufacturing stage. This book expertly combines knowledge gained from years of experience into a single source that will offer the reader a keen insight into understanding the MELD process."—Dr. Chase Cox, Vice President, MELD Manufacturing Corporation, USA

"A thorough book on the emerging additive friction stir deposition technology that is poised to be very disruptive to fusion-based additive manufacturing. It sufficiently covers the benefits and challenges of using the process and provides a solid foundation for further research."—Dr. Michael Eller, Adjunct Professor, University of New Orleans, USA
