Laser Additive Manufacturing of Metallic Materials and Components discusses the current state and future development of laser additive manufacturing technologies, detailing material, structure, process and performance. The book explores the fundamental scientific theories and technical principles behind the elements of laser additive manufacturing, touching upon scientific and technological challenges faced by laser additive manufacturing technology. This book is suitable for those who want to further "understand” and "master” laser additive manufacturing technology and will expose readers to innovative industrial applications that meet significant demand from aeronautical and astronautical high-end modern industries for low-cost, short-cycle and net-shape manufacturing of structure-function integrated metallic components. With the increasing use of industrial applications, additive manufacturing processes are deepening, with technology continuing to evolve. As new scientific and technological challenges emerge, there is a need for an interdisciplinary and comprehensive discussion of material preparation and forming, structure design and optimization, laser process and its control, microstructure and performance characterization, and innovative industrial applications, hence this book covers these important aspects. Highlights an integration of material, structure, process and performance for laser additive manufacturing of metallic components to reflect the interdisciplinary nature of this technology Covers cross-scale structure and performance coordination mechanisms, including micro-scale material microstructure control, meso-scale interaction between laser beam and particle matter, and macro-scale precise forming of components and performance control Explores fundamental scientific theories and technical principles behind laser additive manufacturing processes Provides innovation elements and st
