The book focuses on the integration of advanced manufacturing techniques with novel materials and innovative processing methods. The core objective is to provide a detailed technical overview of how additive manufacturing technologies are evolving to meet the demands of modern materials engineering. Features:Discusses metal additive manufacturing processes, including selective laser melting, electron beam melting, and directed energy deposition. Explores the use of advanced material systems in additive manufacturing, focusing on high-entropy alloys and metal matrix composites. Highlights recent developments, including tailored alloy design, reinforcement strategies, and the influence of process parameters on phase stability, microstructure, and performance. Covers data-driven approaches for process monitoring, defect prediction, parameter optimization, and quality control. Illustrates non-conventional thermal processing methods in additive manufacturing, with a focus on microwave-based cladding, sintering, and heat-treatment techniques. The text is primarily written for senior undergraduates, graduate students, and academic researchers in manufacturing engineering, industrial engineering, production engineering, mechanical engineering, aerospace engineering, and materials science.
