Summary: This study investigates the phase evolution of equimolar powder mixtures of HfC-ZrC-TiC, HfC-ZrC-NbC, and HfC-ZrC-TiC-NbC during pressure sintering. The formation of single-phase substitutional solid solutions based on hafnium carbide occurs in several stages, with simpler solid solutions with fewer components formed first.

Summary: The Fe-Ni-Nb cermet alloys show promising properties as an alternative to cobalt binder in cutting tools. The NbC-10% wt Fe-Ni-Nb cemented carbides prepared by solid state pulsed electrical current sintering exhibit good densification and hardness, making them a viable composite material. However, further improvements can be made to eliminate intermetallic phases and reduce particle size.

Summary: In this study, the properties of Nb/NbC and α-Fe/NbC interfaces in Fe-Nb-C composites were investigated using first-principles calculations. The results showed that C-terminated interfaces exhibited higher stability and greater theoretical tensile strength. In terms of interfacial bonding, Nb-C bonding was found to be better than Fe-C bonding.

Summary: Temperature plays a vital role in the sintering process, as demonstrated by experiments showing rapid grain growth of Fe2O3 grains upon reaching Tammann temperature. Monte Carlo simulations describe the growth process, while molecular dynamics simulations depict grain boundary migrations and atomic motions in the sintering process.Consistent trends of grain growth were observed in experiments and simulations, with grain boundary migrations mainly occurring in the initial stage of sintering.

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: Cu-Ni alloys are thermally and chemically stable, and by adding reinforcing phases, it can improve the wear resistance to develop lighter materials resistant to corrosion and wear. The dominant wear mechanism of Cu10Ni matrix composites is adhesive and oxidative wear, and TiC/Cu10Ni composite has three times more wear resistance than the pure Cu10Ni matrix.

Summary: Continuous fiber-reinforced ceramic matrix composites have promising potential in aerospace, energy, transportation, and other fields due to their excellent thermodynamic properties, but face challenges in grinding due to their high hardness, brittleness, and anisotropy. In this study, abrasive belts were used for the first time to grind Cf/SiC composites, revealing that electroplated diamond abrasive belts show better wear resistance and grinding performance than bonded diamond abrasive belts. During grinding, carbon fibers and the SiC ceramic matrix undergo crushing and plastic deformation, resulting in the formation of flow chips and powder chips, indicating significant ductile material removal behavior of Cf/SiC composites. Furthermore, the ductile material removal behavior becomes more prominent with increasing abrasive wear intensity.

Summary: The study demonstrates successful sintering of TaC and NbC ceramics with high densities, showcasing hardness of 20-25 GPa through reduction in carbon stoichiometry and submicron grain sizes. XRD, SEM, and TGA-DSC were employed to investigate the phenomena during processing, revealing the presence of oxygen impurities in carbide particles and decarburization and oxide segregation during sintering. The effects of decarburization and oxide segregation can be counteracted by carbon excess, but controlling the densification curve can be challenging in such cases.

Summary: The study demonstrates the positive impact of corundum reinforcement on dry sliding wear behavior of LM30 aluminum alloy composites. The composites prepared by stir casting process exhibit uniform distribution of particles and refined microstructure, leading to improved hardness. The addition of corundum results in lower wear rate and coefficient of friction in the composites, and wear mechanism is pressure-dependent.

Summary: Metal Matrix Composites (MMCs) have shown remarkable performance in industrial applications, but have not been fully utilized due to challenges in machining. Finite element simulation is a key tool for investigating machining mechanisms. This research developed 2D and 3D models to simulate the cutting process of silicon carbide reinforced aluminum-based MMC, with both models showing comparable results with experiments.
