“…The results show that the lattice fringes of Gr not only are bent, but also show a large number of dislocations in the lattice fringes of Gr, which are represented by the symbol "T" in Fig. 12(d A good crystallographic matching helps to form a low-energy interface when the two interfaces of different phases are bonded, and this will have enhancing effects on the stability and bonding strength of the interfacial structures [39]. The interface mismatch (δ) is an important parameter to show the matching relationship between the two phases.…”

It is quite difficult to in-situ synthesize graphene directly and economically onto surfaces of copper powders as a reinforcement phase for metal matrix composites, and few studies have been focused on interfacial bonding characteristics between graphene (Gr) layer and copper powders. This paper explores a new strategy using wheat flour as a precursor to in-situ generate graphene on the surfaces of copper powders and investigates interfacial bonding characteristics between Gr and copper powders. Results reveal that the in-situ generation process of graphene on the surfaces of copper powders has two critical stages. The first one is the low-temperature stage (up to 400 ℃), in which H2 reduces the oxide layer (Cu2O) into metallic Cu on the surfaces of the copper powders. The second one is the high-temperature stage (from 289 to 800 ℃), in which the copper powders, with their good catalytic properties, cause the break-up of chemical bonds of the flour and expose the carbon atoms, and

Metal matrix composites (MMCs) are frequently employed in various advanced industries due to their high modulus and strength, favorable wear and corrosion resistance, and other good properties at elevated temperatures. In recent decades, additive manufacturing (AM) technology has garnered attention as a potential way for fabricating MMCs. This article provides a comprehensive review of recent endeavors and progress in additive manufacturing of MMCs, encompassing available AM technologies, types of reinforcements, feedstock preparation, synthesis principles during the AM process, typical AM-produced MMCs, strengthening mechanisms, challenges and future interests. Compared to conventionally manufactured MMCs, AM-produced MMCs exhibit more uniformly distributed reinforcements and refined microstructure, resulting in comparable or even better mechanical properties. In addition, AM technology can produce bulk MMCs with significantly low porosity and fabricate geometrically complex MMC components and MMC lattice structures. As reviewed, many AM-produced MMCs, such as Al matrix composites, Ti matrix composites, Nickel matrix composites, Fe matrix composites, etc., have been successfully produced. The types and contents of reinforcements strongly influence the properties of AM-produced MMCs, the choice of AM technology, and the applied processing parameters. In these MMCs, four primary strengthening mechanisms have been identified: Hall-Petch strengthening, dislocation strengthening, load transfer strengthening, and Orowan strengthening. AM technologies offer advantages that enhance the properties of MMCs when compared with traditional fabrication methods. Despite the advantages above, further challenges of AM-produced MMCs are still faced, such as new methods and new technologies for investigating AM-produced MMCs, the intrinsic nature of MMCs coupled with AM technologies, and challenges in the AM processes. Therefore, the article concludes by discussing the challenges and future interests of additive manufacturing of MMCs.

“…Nanoparticles have a strong effect of microstructure refinement [44][45][46]. Nanoparticles not only can refine the microstructure and control the growth size and morphology of grains [47][48][49][50][51], but also greatly improve the comprehensive mechanical properties of the alloys, especially, high-temperature strength, high-temperature creep, high-temperature wear resistance, impact toughness and fatigue [52][53][54][55][56][57]. Compared with traditional strengthening and toughening technology, the effective control technology by nanoparticles has significant advantages such as not changing the existing casting process and equipment, green and environmental protection [58][59][60].…”

In order to improve the impact toughness and wear resistance of the tool and die steels, this study innovatively prepared strengthened H13 steels with different contents of single-phase TiC and dual-phase TiC + TiB2 through in situ nanoparticle/Al master alloys at room temperature. The microstructure evolution and mechanical properties as well as wear resistance were investigated. Results indicate that the H13 steel with 0.02 wt.% dual-phase TiC + TiB2 nanoparticles has a more uniform and finer microstructure, and the mechanical properties and wear resistance are significantly improved. The yield strength, maximum tensile strength, breaking strain, uniform elongation, product of strength plasticity, and unnotched and U-notched impact toughness of H13 steel with 0.02 wt.% dual-phase TiC + TiB2 are higher than that of H13 steel. In addition, the volume wear rate, maximum scratch depth and width reach 7.1 × 10−11 m3/m, 6050 nm and 90 μm, respectively, which are reduced by 44.5%, 30.1% and 45.5% compared with that of H13 steel. Refining the microstructure and improving impact toughness and wear resistance of H13 tool steel through trace nanoparticles can provide important inspiration for industrial applications.
