Metal matrix composites (MMCs) are promising alternatives to metallic alloys. Their high strength-to-weight ratios; high temperature stabilities; and unique thermal, electrical, and chemical properties make them suitable for automotive, aerospace, defense, electrical, electronic, energy, biomedical, and other applications. The wide range of potential combinations of materials allows the properties of MMCs to be tailored by manipulating the morphology, size, orientation, and fraction of reinforcement, offering further opportunities for a variety of applications in daily life. This Special Issue, “Metal Matrix Composites”, addresses advances in the material science, processing, material modeling and characterization, performance, and testing of metal matrix composites.

Metal matrix composites (MMCs) are engineering materials in which a hard ceramic component is dispersed in a ductile metal matrix in order to obtain characteristics such as hardness and corrosion resistance. Corrosion resistance is one of the important properties of nanocomposites; however, the corrosion mechanism of the Al- SiC nanocomposite has not yet been determined. .In this study, bulk Al-5% SiC nanocomposite was prepared using mechanical alloying and the hot press method. Corrosion behavior was then investigated using EIS techniques such as Nyquist and the Bod diagram. A larger charge transfer resistance was found for the Al- SiC nanocomposite by the EIS diagrams, confirming its corrosion resistance in a 3.5wt% NaCl solution.

The Difference

The paper use the finite element method, simulating the solidification process of metal matrix composite. Obtain the changing of temperature field about the solidification process and some temperature curve for special nodes. The results show that, due to the difference of heat transfer coefficient about the matrix and the metal the solidification process for composite materials showed the irregular temperature cloud, namely nonlinear temperature distribution. The simulation actually provides some guidance for synthesis of metal composite materials.

Aluminium metal matrix composites are being widely investigated with Carbon Nanotubes (CNTs) as one of their reinforcing agents. This is done in order to improve the mechanical strength of the composite. Various studies on this concept have already been recorded. In this study, Aluminium has been reinforced with CNTs using powder metallurgy technique. The powders of aluminium and CNT are ball milled, compacted in a die made up of die steel, and then sintered. The specimens thus obtained were subjected to hardness, compression and chemical tests and the values were compared with pure aluminium specimen fabricated by same technique. The study indicated that there was no improvement in hardness of the composite on addition of CNT. The compressive strength of the composite was increased by 143.58 MPa. The microstructure of pure aluminium and Al-CNT composite had fine grains of pure aluminium particles and Al-Si eutectic particles throughout the matrix phase.

New developments in material technology aids in the investigations, reinforcements of new materials which replaces existing materials for various applications. Among those, composite materials play an important role which is a combination of two or more materials with different physical and chemical properties. This research focused on developing an aluminium metal matrix composite (AMMC) material made by wrought aluminium alloy with various weight fractions of aluminium oxide to make five different forms of composites. In this research stir casting process was used. The reinforced composites were tested for their tensile and impact strength properties. The results show that composite with a higher percentage of aluminium oxide has high tensile and impact strength properties than other composites.

Computational homogenization provides an excellent tool for the design of composite materials. In the current work, a computational approach is presented that is capable of estimating the elastic and rate-independent plastic constitutive behavior of metal matrix composites using finite element models of representative volume elements (RVEs) of the composite material. For this purpose, methodologies for the generation of three-dimensional computational microstructures, size determination of RVEs and the homogenization techniques are presented. Validation of the approach is carried out using aluminum–alumina composite samples prepared using sintering technique. Using the homogenized material response, effective constitutive models of the composite materials have been determined.
