Metal matrix composites (MMCs) have long been the subject of extensive research and industrial development. Application areas, for which the mechanical strength of pure metals or alloys are not sufficient, require the use of MMCs–materials, in which reinforcements of different types are distributed in metal matrices and act as load-bearing elements and/or additives modifying the structure and properties of the matrix itself. Distribution of reinforcements in a metal matrix is a key structural feature, determining the mechanical behavior of MMCs. Recent studies have shown that a uniform distribution of the reinforcement particles is not an answer to all property requirements. In order to increase the ductility and damage tolerance, trimodal composites featuring reinforcement-free regions and composites with network distribution of reinforcements have been developed. In MMCs produced by powder metallurgy, interesting microstructure design possibilities appear when the shape of powder agglomerates is tailored and the bulk composites are allowed to inherit the structural features of the powders.
Along with traditional ceramic particulate reinforcements, new types of reinforcing phases have gained attention: Graphene platelets, carbon nanotubes, particles of stronger metals (relative to the matrix metal) and particles of metallic glasses. In close connection to attempts to harness metastable compositions and nano-sized morphological features in MMCs are the developments of non-equilibrium consolidation methods enabling the grain size control and presevation of metastable characteristics of the materials in the bulk state. Fundamental studies of the effect of the composition and physical properties of the reinforcement on the consolidation behavior of MMCs in non-equilibrium processes should be futher extended. Novel in situ synthesis techniques are being developed to achieve intermixing of the target phases at the nanoscale. In MMCs designed for functional applications, the property trade-off has to be tackled: Positive gains in mechanical strength, stiffness and wear resistance often come at a price of an electrical conductivity loss. MMCs with layered structures, MMC coatings and functionally graded MMCs present promising directions to follow in order to achieve desired property combinations.
This Special Issue aims to become a forum for active discussions of advances in the synthesis, structural design and property tailoring of MMCs to highlight current scientific and technological challenges that remain to be solved in this area of materials science.
