Special Issue Information

Dear Colleagues,

Metal matrix nanocomposites (MMNCs) are of great interests, owing mainly to their superior features, which are suitable for different applications, such as functional and structural applications. On the other hand, during the last two decades, in order to fulfil new criteria of working conditions for electronic devices, and also to broaden their industrial applications in different fields, such as automotive, aerospace and electronic packaging, the development of new materials has generated considerable research interest. The technology advancements and, as a result, the need for devices with high efficiencies have encouraged this trend. Nevertheless, the most accurate requirements for the choices of suitable matrix, reinforcement, and techniques (processing and post-processing) are not completely defined. Moreover, new facilities, in the case of metal matrix nanocomposites, are always suggested by the continuous progress of new materials, particularly in the range of the nano-scale. For this reason, it is very interesting to deeply investigate the connection between the features; constituents, including matrix, reinforcement, interphases, and also production techniques.

This Special Issue aims to provide contributions focusing on the emerging trends, both in graphene nanoplatelets and metal matrix composite development, and in composite manufacturing technologies. Original articles and review papers will deal with the following themes, without being limited to them: Processing and characterization of any type of graphene and metal matrices, microstructure evaluation, physical and structural characterization and testing, optimization of properties and processes including calculations, simulation of properties over length-scales, and novel applications of graphene-reinforced metal matrix nanocomposites. Contributions on multiscale composites, advanced manufacturing processes, novel joining methods, cutting-edge joining and assembly processes are also encouraged. Technological advancements and, as a result, the need for devices with high efficiencies are encouraged.

Al matrix nanocomposites are interestingly employed in the automotive, military, aerospace and electronics packaging industries. In this study, Graphene Nanoplatelets (GNPs) reinforced AlSi10Mg nanocomposites were produced via powder metallurgy. The effect of GNPs content on density, microstructure and mechanical characteristics of the AlSi10Mg/GNPs nanocomposites was investigated systematically. To this aim, AlSi10Mg/GNPs nanocomposites reinforced with 0.5, 1.0 and 2.0 wt.% of GNPs were produced by wet mixing method following by hot compaction at 600 °C. To evaluate the effect of GNPs on mechanical properties of the as-fabricated nanocomposite, Vickers hardness and tensile properties of composites analyzed at room temperature. According to the results, it was found that the fabrication of AlSi10Mg/GNPs nanocomposites is faced with several challenges such as agglomeration and non-uniform dispersion of GNPs that should be addressed to achieve the desirable thermal and mechanical properties. For instance, surprisingly, it is revealed that the mechanical and thermal properties of nanocomposites were deteriorated in the presence of a high quantity of GNPs (>1.0 wt.%), which can be attributed to the GNPs agglomeration and accordingly introduction of internal porosity in the nanocomposite. The relatively low fraction of GNPs can uniformly be dispersed in the matrix and improve the performance of the nanocomposite. Full article
