This book introduces the fundamentals and principles of laser shock peening (LSP) for aeronautical materials, emphasizing innovations in theory and methods related to LSP-induced gradient structures in titanium and Ni-based alloys commonly used in aircraft industries. Key topics include the characteristics of laser shock waves, the formation mechanisms of gradient structures, and the strengthening-toughening mechanisms associated with these structures. The research presented is backed by extensive experimental data demonstrating LSP's significant effectiveness in enhancing the fatigue performance of metal parts, with successful applications in the aerospace sector. The content is valuable for researchers in LSP, mechanical strength, machine manufacturing, and surface engineering, as well as those studying laser shock waves and materials science. The book covers various aspects, including the characteristics of laser-induced plasma shock waves, the gradient microstructure characteristics and formation mechanisms in titanium alloys, and the improvements in high cycle and high temperature fatigue performance in these materials due to LSP-induced gradient microstructures. It also explores the mechanical behavior and strengthening mechanisms of these microstructures and examines the compound process of LSP and its effects on aero-engine blades.
