Developments in AM of Metals and Metal Matrix Composites

The metal additive manufacturing (MAM) field has created interest across industries, particularly aerospace, defense, and automotive sectors, due to its capability to fabricate components with complex geometries and improved performance with weight reductions. Significant progress in MAM has been made in manufacturing methods, materials, characterization, and performance of the fabricated parts. In addition to metals and their alloys, metal matrix composites (MMCs) have been attempted through additive manufacturing (AM) in recent decades. This chapter presents a detailed review of advancement in AM of MMCs and resultant microstructure and properties over conventionally processed MMCs. Moreover, the limitations and challenges involved in the fabrication of MMCs through AM are discussed and future research directions are highlighted.
