Abstract :
: Metal matrix composites (MMCs) are widely used in a variety of advanced industrial fields because of their high
modulus and strength, in addition to other desirable properties at high temperatures, such as wear resistance and corrosion
properties. These properties encourage the material to be used in a variety of applications. MMCs possess these qualities,
which is why this is the case. For the past few decades, the method of additive manufacturing (AM) has been the focus of
interest as one of the prospective technologies that can be applied to construct MMCs. This attention has been directed
toward the manufacturing approach. The field of additive manufacturing (AM) for metal-metal composites (MMCs) is the
subject of this article, which examines the current advancements and activities that have taken place in this field. The various
additive manufacturing (AM) technologies that are currently available, the various types of reinforcement, the preparation
of feedstock, the fundamentals of synthesis in the AM process, typical AM-produced MMCs, the strengthening mechanisms
of MMCs, the challenges that are required to fabricate MMCs, and potential interests in the field are all highlighted in this
article. The AM method of manufacturing MMCs displayed mechanical properties that were equivalent to or even superior
to those of the conventionally manufactured ones. This was proved when compared to the MMCs that were created using
the regular MMC production procedure. This occurred as a result of the reinforcement being distributed uniformly
throughout the material and the tiny microstructure. In addition, the technology of additive manufacturing can be applied
to construct MMC lattice structures and geometrically complex components of MMC items. Additionally, it can be utilized
to generate bulk MMCs with a substantially lower porosity. According to what was stated earlier, it has been noted that a
significant number of AM-fabricated MMCs have been made. These MMCs include titanium matrix composites, aluminum
matrix composites, nickel matrix composites, and iron matrix composites, amongst others. Both the technology and the
parameters of additive manufacturing (AM) are highly dependent on the types and contents of reinforcements that are
chosen. This, in turn, has an impact on the qualities of the MMCs that are produced by AM. Orowan strengthening, load
transfer strengthening, dislocation strengthening, and Hall–Petch strengthening are all examples of different sorts of
strengthening processes that have been identified in such MMCs. These four separate pathways have been identified as
strengthening mechanisms. There are, however, a number of drawbacks that exist between the AM technologies and the
regular manufacturing techniques, and these drawbacks can be solved for the properties of MMCs. Nevertheless, there are
a lot of opportunities for improvement. Despite this, there are still more challenges to overcome: concerns about AMproduced MMCs, including their intrinsic properties in connection with AM technologies, new methods and tools for
studying them, and AM process problems. Only these are some of the issues being addressed at this critical time. Thus, the
paper finishes by examining AM of MMCs' difficulties and future interests. This concludes the paper. This article mentions
additive manufacturing, feedstock, metal matrix composites, microstructure, and performance.
