Special Issue Information

Dear Colleagues,

Metal matrix composites (MMCs), in bulk or coating, have long been attracting interest, as they offer the opportunity to fulfil a broad array of functions (e.g., exhibiting specific thermal properties, or as self-cleaning, self-lubricating or self-healing materials) and requirements (i.e., facing higher service temperature, corrosive environment and/or increased mechanical load). This versatility of metal matrix composites can be ascribed, not only to the vast choice of combinations of metallic matrix and second phases, but also to the great diversity of processing methods, including solidification processes, powder metallurgy, as well as additive manufacturing and severe plastic deformation (SPD) processes, which have opened even more possibilities. In particular, additive manufacturing allows to fabricate composite parts with complex geometry. With the latter process, the control of reactions between the second phases and the molten metal may be challenging, but these reactions also offer the opportunity for the in-situ synthesis of well distributed nano-scale second phases. With regards to severe plastic deformation processes, they tend to avoid harmful interfacial reactions as well as solidification defects since they proceed in the solid state. The deformation generated during these processes offers the possibility to associate immiscible materials, to get out-of-equilibrium structures, as well as nanostructures, nanocomposites and even novel MMCs with advanced enhanced properties. This Special Issue, hence, aims at showcasing the latest developments in the fabrication of metal matrix composites, with a particular attention for the new possibilities (in terms of microstructures, properties and functionalities) offered by the use of additive manufacturing and SPD processes.

In this study, a Ti composite reinforced with 5 vol. % (TiBw + TiCp) was fabricated by an in situ casting route. Open die forging in (α + β) phase region was conducted on the composite casting. The microstructures of the as-forged composite pancake are inhomogeneous in terms of matrix microstructure and distribution of reinforcements. The matrix grains are gradually refined from the periphery to centre of the pancake. The reinforcements TiBw and TiCp tend to be uniformly distributed in the centre region. It is suggested that the microstructure difference can be mainly ascribed to the temperature variation from the periphery to the centre. The tensile testing results show that the centre region of the composite pancake exhibits higher strength than the peripheral region. The mechanical behaviour of the composite pancake with the temperature is discussed. Full article

Two-dimensional graphene nanoplatelets with unique electrical, mechanical and thermophysical characteristics are considered as an interesting reinforcement to develop new lightweight, high-strength, and high-performance metal matrix nanocomposites. On the other hand, by the rapid progress of technology in recent years, development of advanced materials like new metal matrix nanocomposites for structural engineering and functional device applications is a priority for various industries. This article provides an overview of research efforts with an emphasis on the fabrication and characterization of different metal matrix nanocomposites reinforced by graphene nanoplatelets (GNPs). Particular attention is devoted to find the role of GNPs on the final electrical and thermal conductivity, the coefficient of thermal expansion, and mechanical responses of aluminum, magnesium and copper matrix nanocomposites. In sum, this review pays specific attention to the structure-property relationship of these novel nanocomposites. Full article

This article provides an overview of research efforts with an emphasis on the fabrication of metal matrix nanocomposites (MMNCs) reinforced by graphene nanoplatelets (GNPs). Particular attention is devoted to finding the challenges in the production of MMNCs through the powder metallurgy techniques. The main technical challenges can be listed as: (I) reinforcement selection; (II) dispersion of reinforcement within the matrix; (III) reactivity between the reinforcement and matrix; (IV) interfacial bonding; (V) preferred orientation of reinforcement. It is found that some of these difficulties can be attributed to the nature of the materials involved, while the others are related to the preparation routes. It is reported that the challenges related to the process can often be addressed by changing the production process or by using post-processing techniques. More challenging issues instead are related to the composition of the matrix and reinforcement, their reactivity and the dispersion of reinforcement. These topics still bring significant challenges to the materials scientists, and it would be worth mentioning that the fabrication of MMNCs with a uniform dispersion of reinforcement, strong interfacial bonding, without detrimental reactions and improved isotropic properties is still a puzzling issue.
