Summary: This study investigated the microstructure and tribological characterization of in-situ TiC and gamma'-Ni-3(Al,Ti) reinforced gamma-Ni(Al,Ti) matrix composites. The addition of 10 wt% MAX phase precursor resulted in the highest hardness and all reinforced composites showed improved wear resistance. The formation of a lubricious layer during sliding and good in-situ bonding between Ni/reinforcement phases were identified as the main reasons for the enhanced wear resistance.

Summary: The mechanical, corrosion, and wear features of AA1050/TiC composites were studied through molecular dynamics simulation. Powder metallurgy and accumulative roll bonding were used to fabricate the composites. It was found that increasing the Nano TiC Wt.% enhanced wear and corrosion resistance, density, hardness, and strength while reducing elongation, bonding strength, and electrical conductivity.

Summary: In this study, FeCoNi1.5CrCu/Al composites with excellent mechanical properties were successfully prepared using microwave sintering technology. It was found that the material maintained a fine and uniform microstructure during microwave heating. The mechanism of interface formation revealed the presence of an atomic diffusion layer with a BCC solid solution structure between the high entropy alloy particles and the matrix, which significantly enhanced the interfacial bonding performance.

Summary: Heterostructured Al/10 vol% (TiC-GNPs) composites were produced by powder metallurgy (PM) with varying TiC-to-GNPs volume ratios. The dispersion of TiC in the matrix improved and the heterostructure of the composite was optimized as the TiC-to-GNPs ratio decreased. The compressive properties of the composite were significantly improved, achieving a balance between increased strength and retained ductility. However, the compressive properties decreased dramatically when the GNPs content reached 2 vol% due to the presence of GNPs agglomerates.

Summary: The use of SiCp/2024Al composite particles as deformable reinforcement in metal matrix composites showed higher toughness and comparable tensile strength compared to SiCp/Al composites with the same SiC particle content. The main deformation mechanism shifts with the increase in matrix strength, and uniform strain distribution was observed in the deformable particle/2024Al composites.

Summary: TiC-reinforced metal matrix composites were fabricated by laser cladding with FeCrCoNiAlTiC high entropy alloy powder. The coating layer under the effective heat input of 50 J/mm(2) had relatively homogeneous blocky particles of several micrometers in size, with a micro-hardness value over 900 HV, and nano-hardness of the reinforcing particles and the matrix were 17 GPa and 10 GPa, respectively.

Summary: This study focused on fabricating and characterizing a new type of composite invar material that combined near-zero thermal expansion with functional properties, achieved by embedding particles of negative thermal expansion SmB6 in an aluminum matrix. Experimental data and theoretical models showed that the composite material exhibited invar behavior up to around 60 K, with a zero coefficient of thermal expansion near 45 K, providing an extended temperature range compared to pure aluminum.

Summary: This study investigated the mechanical and corrosion properties of Al + 20 vol% (TiC + TiB2) composites containing different amounts of MWCNTs produced by mechanical alloying and spark plasma sintering processes. The results showed that the addition of MWCNTs improved the hardness, Young's modulus, and corrosion resistance of the composites.

Summary: The study investigated the wear behavior and friction performance of Cu/TiC–graphite hybrid systems with different graphite contents, finding that increasing graphite content can reduce friction coefficient and wear rate, and alter the wear mechanism of pure copper to abrasion and delamination. The systems with graphite additions showed partial lubrication of the contact surfaces.

Summary: By designing a reinforcing phase in unweldable SiCp/2xxxAl alloy, the mechanical properties of high-strength lightweight SiCp/Al joints can be improved. In situ generation of L12-(Al,Si)3Ti and TiC from Si and C precipitated from SiC particles, as well as the formation of Al3Ti on the surface of SiC particles, enhances load transfer and increases the yield strength of the joints through the combined effects of nanoscale TiC phase and high density of geometrically necessary dislocations.

Summary: This article presents the features of in-situ synthesis, microstructure evolution, and mechanical properties of TiC-Cu composites obtained by mechanical milling and spark plasma sintering (SPS). Different carbon sources were compared for their influence on the composite mixtures, with the conclusion that carbon black and nanodiamonds facilitate faster conversion of reactants compared to graphite. The TiC-Cu composite obtained showed a relative density of 95%, impressive strength and hardness properties, and an unconventional microstructure.
