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.

About the Author

Hang Yu

Hang Z. Yu is an Assistant Professor of Materials Science and Engineering at Virginia Tech. He received his Bachelor’s degree in physics from Peking University in 2007 and his Ph.D. degree in materials science and engineering from Massachusetts Institute of Technology in 2013. The primary interest in Dr. Yu’s research group at Virginia Tech lies in advanced manufacturing of structural metals and multi-functional metal matrix composites, with the current focus on solid-state additive manufacturing via additive friction stir deposition. As a pioneer of the field, Dr. Yu has published the first review paper on additive friction stir deposition and has explored multiple aspects of the process, including integration of data-driven and physically-based approaches for process control (temperature, material flow, distortion), design of innovative microstructures of multi-phase alloys, synthesis of new hybrid materials and composites, as well as application of the technology in large-scale repair, cladding, and materials recycling.
