What is Infiltration

A substantial effort has recently been made to fabricate numerous combinations of metal matrix composites. Aluminium metal matrix composite (AlMMCs) has been extremely popular among MMCs and is best suited for lighter materials in various industries and domestic applications. AlMMCs have significant faults in terms of production costs. More research is needed to develop AlMMCs that are both economic and suitable for a wide range of industrial applications. AlMMCs are manufactured using the casting technique, solid-state processing, infiltration method, accumulative roll bonding, spray deposition, friction stir processing, and other technologies. This chapter will summarize the current state of the art in aluminum-based metal matrix composites, as well as recent developments in processing and application, all in one location, so that relevant stakeholders can benefit the most and new advancements on such themes can be fostered.
