Fatigue Behavior of Metallic Materials Subjected to Warm Laser Shock peening

This book begins by introducing the fundamental principles of Warm Laser Shock Peening (WLSP) and its influence on the fatigue behavior of metallic alloy materials. As a surface enhancement technique derived from Laser Shock Peening (LSP), this book focuses on how thermomechanical coupling effects induce microstructural modifications and residual compressive stresses to enhance fatigue performance, especially in aerospace alloys such as aluminum and titanium alloys. The main content of this book includes the characteristics of laser-induced shock waves at elevated temperatures, the thermomechanical coupling modification mechanisms of WLSP, and the underlying mechanisms behind fatigue life extension. This book presents extensive experimental data that demonstrate the significant effectiveness of WLSP in improving the fatigue resistance of metallic alloys. These findings offer theoretical guidance and a data foundation for applying WLSP in aerospace engineering. This book is highly valuable for researchers engaged in LSP, fatigue behavior, mechanical manufacturing, and surface engineering, as well as for students specializing in laser shockwave technology and materials science. The analyses presented in this book will help readers gain deep insights into the fatigue resistance mechanisms induced by WLSP’s thermomechanical coupling effects and may inspire further interest in advancing this technology.
