“…Conventional approaches to metal matrix composites focus on the homogenization and recombination of a single-phase, single-scale reinforcement matrix. This approach aims to address problems such as insufficient matrix density, agglomeration of nano-reinforcement, structural damage, and interfacial reactions [18,19]. The concept of "homogeneous composite", inspired by biological composites, has undergone significant development leading to unique composite configurations [20][21][22].…”

In response to the growing demand for high-strength and high-toughness materials in industries such as aerospace and automotive, there is a need for metal matrix composites (MMCs) that can simultaneously increase strength and toughness. The mechanical properties of MMCs depend not only on the content of reinforcing elements, but also on the architecture of the composite (shape, size, and spatial distribution). This paper focuses on the design configurations of MMCs, which include both the configurations resulting from the reinforcements and the inherent heterogeneity of the matrix itself. Such high-performance MMCs exhibit excellent mechanical properties, such as high strength, plasticity, and fracture toughness. These properties, which are not present in conventional homogeneous materials, are mainly due to the synergistic effects resulting from the interactions between the internal components, including stress–strain gradients, geometrically necessary dislocations, and unique interfacial behavior. Among them, aluminum matrix composites (AMCs) are of particular importance due to their potential for weight reduction and performance enhancement in aerospace, electronics, and electric vehicles. However, the challenge lies in the inverse relationship between strength and toughness, which hinders the widespread use and large-scale development of MMCs. Composite material design plays a critical role in simultaneously improving strength and toughness. This review examines the advantages of toughness, toughness mechanisms, toughness distribution properties, and structural parameters in the development of composite structures. The development of synthetic composites with homogeneous structural designs inspired by biological composites such as bone offers insights into achieving exceptional strength and toughness in lightweight structures. In addition, understanding fracture behavior and toughness mechanisms in heterogeneous nanostructures is critical to advancing the field of metal matrix composites. The future development direction of architectural composites and the design of the reinforcement and toughness of metal matrix composites based on energy dissipation theory are also proposed. In conclusion, the design of composite architectures holds enormous potential for the development of composites with excellent strength and toughness to meet the requirements of lightweight structures in various industries.

“…39 P/M fabrication route for composite materials generally involves mixing the powders of matrix and reinforcement uniformly followed by cold pressing, hot pressing, and then sintering. 40 P/M process is a versatile technique associated with some inherent advantages such as possibility of modification and optimization of production parameters based on desired properties, possibility of using ceramic–metal combinations not viable by liquid-state routes and producing near-net shaped components. Some of the drawbacks include cost-ineffectiveness for small productions, oxidization of powders which demands inert/protective gas conditions, and high porosity content (inevitable in P/M techniques) that leads to degradation in properties, especially the drastic reduction in ductility.…”

“…Some of the drawbacks include cost-ineffectiveness for small productions, oxidization of powders which demands inert/protective gas conditions, and high porosity content (inevitable in P/M techniques) that leads to degradation in properties, especially the drastic reduction in ductility. 40,41 Depending on matrix and reinforcement materials, shape and size of powders, and the selected fabrication technique, MMCs can be designed and produced for different applications. In the present study, the effect of volume fraction of TiB 2 on mechanical properties and microstructure of the fabricated Fe–TiB 2 was investigated.…”

Recently, ultra-high-temperature ceramics have received abundance attention due to growing demand of new materials for extreme service conditions. In this study, titanium diboride particles as an ultra-high-temperature ceramic material have been used to reinforce iron matrix to fabricate a metal matrix composite. Iron–titanium diboride composite samples with different volume fractions of titanium diboride fabricated using powder metallurgy route. Physical, microstructural and mechanical properties of metal matrix composite were studied. The results indicated that addition of titanium diboride only up to 20 vol% increased mechanical properties of the processed composite. Microstructure-based finite element analysis could verify the experimental results.
