摘要

Hybrid metal matrix composites are structured with two or more types of in-situ particles formation to take the synergistic behaviour of the different phases in metal matrix composites (MMCs). The retention of MMCs within wire arc additive manufacturing (WAAM) presents a set of challenges that are not addressed using frameworks developed in previously studied MMC alloys. This review provides a comparative and detailed overview of the WAAM–MMCs, subjected to a strong interrelation between arc physics, melt pool dynamics, reinforcement transport, interfacial reactions, and defect formation mechanisms, rather than conventional MMCs or WAAM MMC systems.
