Metal Matrix Composites: Analysis, Modeling, Observations, and Interpretations

To explore the growth of knowledge related to research on metal matrix composite materials, the symposium Metal Matrix Composites: Analysis, Modeling, Interpretations and Observations was held during the TMS 2020 Annual Meeting & Exhibition in San Diego, CA, USA, February 23-27, 2020. In the following article by Ramasis Goswami et al. on "Role of Microstructure and Interfaces in Governing the Mechanical Properties of Nano-composites Manufactured in the Solid State", the authors attempt to study, record, and report the microstructure and interfacial characteristics of boron carbide-nickel (B4C-Ni) and silicon carbideboron carbide (SiC-B4C) composites processed in the solid state at relatively high pressure using transmission electron microscopy (TEM). In this paper, two popular magnesium cast alloys, namely Mg-Al-Mn alloy (AM 100) and Mg-Zn-Cu alloy (ZC63), and their saffil alumina short fiber-reinforced composite counterparts were investigated to study their microstructure, mechanical properties, and corrosion resistance. In the subsequent article on "Influence of Constrained High Pressure Torsion on Microstructure an Mechanical Properties of an Aluminum Based Metal Matrix Composite," Korznikova et al. fabricated multilayered aluminum-copper composites successfully using the technique of constrained high-pressure torsion by applying a Bridgeman anvil-type unit with an applied pressure of 6.0 GPa after ten turns.
