Abstract
This chapter discusses the concepts, casting techniques and applications of functionally
graded materials metal matrix composites (FGMMCs). Considerations were given to
bulk functionally graded aluminium matrix composites (FGAACs) production processes.
Liquid-metal forging processes of FGAACs fabrication, such as infiltration process, squeeze
casting, friction casting or compocasting, stir, and centrifugal casting were discussed. The
chapter provides basic concepts of the processes and overview of their processing param-
eters, such as mould rotational speed; reinforcement particles size and volume; degassing
method; melting and pouring temperatures; pressure; and stirrer. The study notes that
functionally graded materials (FGMs) are commonly used in automotive, aircraft, aviation,
chemical, medical, engineering, renewable energy, nuclear energy, and optics electronics
industries.
