Additive Manufacturing of High-Performance Metallic Materials outlines the state-of-the-art on AM in high performance materials utilizing the two most industrially interesting routes of powder bed fusion (PBF) and directed energy deposition (DED). The book delves into Feedstock, Processing, Monitoring and control, Modeling and simulation, and Surface and thermal post-treatments. It specifically addresses materials and the most relevant and high performance applications, namely Ni-based alloys and Titanium alloys, and also provides insights into potential applications through illustrative case studies. With each chapter contributed by experts in the field, this work will serve as a comprehensive resource for graduate students and practitioners alike.
