Metal matrix composites (MMCs) have a wide range of potential applications in aerospace,
aviation, marine, automotive, and biomedical fields due to their properties such as high
mechanical strength, superior corrosion, and wear resistance. However, the difference in the
coefficient of thermal expansion between the matrix and reinforcement phases can lead to
defects such as segregation, delamination, or porosity during the production process and during
use. These defects limit the performance of the materials and restrict the use of MMCs in many
applications. In recent years, compositionally graded metal matrix composites (CGMMBs)
have been developed to mitigate these structural problems and improve mechanical behavior. In
these materials, the composition gradually changes from the surface to the core, allowing for the
coexistence of different compositional properties in different regions. The graded structure
allows for increased hardness and wear resistance at the surface while maintaining toughness
and impact resistance in the interior. This allows CGMMBs to exhibit more balanced and
versatile mechanical performance than traditional homogeneous composites. With
technological advancements, the production of materials can be achieved through different
methods. In particular, powder metallurgy and additive manufacturing techniques offer
significant advantages in terms of composition control, microstructural homogeneity, and
improved interfacial quality. This study comprehensively evaluates the production principles of
graded metal matrix composites, the technical advantages of the methods used, and their
potential applications in various engineering fields.
