Summary: In this study, SiC whisker-reinforced Al2O3/Cu composites were fabricated by powder metallurgy and hot extrusion. The results showed that the hybrid reinforcement of particles and whiskers significantly enhanced the mechanical properties of the composites. Moreover, the SiC whiskers led to electrical conductivity anisotropy in the composites.

Summary: In this paper, copper-tungsten composites were synthesized by preparing porous tungsten skeletons through directional solidification, ice sublimation, and heat treatment, followed by infiltration of copper. The Cu-15 vol% W composites exhibited alternately patterned Cu and W microstructures and showed a good combination of electrical conductivity and hardness. The strengthening mechanisms were attributed to the tungsten network structures formed in the copper matrix.

Summary: The homogeneous distribution of carbon nanotubes (CNTs) and good interfacial bonding in Cu matrix are crucial for obtaining excellent properties of CNT/Cu composites. In this study, silver-modified CNTs (Ag-CNTs) were synthesized using a simple and efficient method, and Ag-CNTs/Cu composites were fabricated through powder metallurgy. The modification with Ag effectively improved the dispersion and interfacial bonding of CNTs. Compared to CNTs/Cu counterparts, Ag-CNTs/Cu samples exhibited significantly improved properties, including an electrical conductivity of 94.9% IACS, a thermal conductivity of 416 W/m center dot k, and a tensile strength of 315 MPa. The strengthening mechanisms were also discussed.

Summary: The study found that copper mesh-carbon/carbon (C/C) composite and copper foam-C/C composite have more advantages over pure carbon strip in terms of electrical conductivity, compact strength, and wear resistance. Carbon fibers are able to withstand failure energy and block crack growth during impact and current-carrying friction tests, thereby enhancing mechanical strength and wear resistance. Additionally, the random distribution of short-cutting carbon fibers is conducive to the formation of a smooth tribolayer for copper foam-C/C composite.

Summary: The role of materials and materials science is increasingly important in engineering and technology, especially with the use of metal matrix composites. These composites have shown potential in advanced applications where conventional materials were not suitable. The properties of the composites can be altered by adding various reinforcements, such as carbon nanotubes, to achieve desired properties. This study focuses on the processing of copper-carbon nanotube composites and their microstructures, properties, and correlation with reinforcement percentages and processing methods.

Summary: The design of high-performance overhead aluminum wires is challenging due to the trade-off between strength-ductility and strength-electrical conductivity. In this study, in-situ halide salt reactions were used to introduce dual-size TiB2 particles into 6201 alloy, resulting in improved mechanical properties with slight sacrifice of electrical conductivity. The addition of Al-3B master alloy successfully optimized the electrical conductivity, as well as maximizing the strength and ductility.

Summary: The microstructural evolution of graphene nanoplatelets (GNPs) reinforced magnesium matrix composites (MMCs) fabricated by thixomolding process was investigated. The GNPs penetrated through the grain boundaries and embedded in two adjacent grains, providing efficient barriers to dislocations and contributing to their accumulation. Additionally, finer MgO particles and elongated Mg17Al12 were anchored around the GNPs, improving interfacial load transfer and shear strength. This unique distribution characteristic of GNPs significantly enhanced the mechanical properties of the composites and has potential implications for structural design.

Summary: Metal matrix composites with Al2O3 reinforcement were produced using liquid metal infiltration method in two stages, with preheating and sintering of preforms before casting showing the best mechanical and tribological properties. In situ melting during casting process led to decreased mechanical strength and wear resistance due to excessive oxidation.

Summary: Research shows that, in addition to density, microstructural aspects have significant effects on the conductivity and thermal erosion resistance of W-Cu composites. Larger copper channels in W-Cu composites provide higher conductivity and erosion resistance, and the uniformity of channel walls has the same effects.

Summary: This work investigates the influence of the initial state of Ti-Si3N4 system on the prepared composites. It is discovered that the size of Si3N4 particles affects the formation of core-shell particles and the aggregation of TiN particles. Furthermore, ball-milling Ti-Si3N4 powders can improve the distribution of TiN, but excessive ball-milling time hinders the dispersion of the enhanced phase. The study demonstrates that ball-milling Ti-Si3N4 mixed powder for 6 hours in a vacuum environment with a ball-to-weight ratio of 6:1 and a milling speed of 300 rpm effectively promotes the uniformity of the microstructure of the TiN-Ti5Si3 reinforced Cu matrix composites.

Summary: Woven carbon fibers reinforced Al-matrix composites were successfully prepared using a liquid metallurgy process in a pulsed magnet field (PMF). The introduction of PMF significantly improved the infiltration result and led to a substantial increase in the bending strength of the obtained composite. The electromagnetic infiltration morphology in PMF exhibited gradient and synchronization characteristics, distinguishing it from the step-by-step characteristic of spontaneous infiltration morphology.
