“…Fig. 5a reveals a uniform microstructure with uniform grain size, owing to the presence of appreciable TiC content [41], which inhibits grain growth, thereby resulting in a fine-grained microstructure. A similar microstructure was reported in studies conducted by Russias et al [42] and Chen et al [43].…”

“…The in-situ synthesis method has the advantages of small particle size, regular shape, high stiffness, and clean interface [20][21][22], and has become an important preparation method for high-performance particle-reinforced aluminum-matrix composites. The in-situ synthesized reinforced particles in aluminummatrix composites mainly include TiB 2 , TiC, Al 2 O 3 , ZrB 2 , TiN, and TiAl 3 [23][24][25][26][27]. Among them, TiC particles have advantages such as a high melting point and high hardness, which are widely chosen as a hard ceramic reinforcement.…”

The work aims to enhance and modify the armature surface in electromagnetic rail launch systems and improve its anti-ablation performance to better resist the impact ablation effects of high-temperature and high-speed arcs during the electromagnetic rail launch process and improve launch reliability. TiC particles are widely selected as metal material reinforcements, with advantages such as high melting points and high hardness. In this paper, the arc impact model of pure aluminum alloy and the arc impact model of TiC particle-reinforced aluminum-matrix composite coating–pure aluminum alloy were constructed based on molecular dynamics simulation. The ablation resistance of the material was evaluated by analyzing the depth of arc impact, the mass loss of the model, the number of gasification atoms, and the surface temperature of the material. The protection mechanism of the modified layer on the substrate was revealed by analyzing the damage degree of the surface and subsurface of the material after arc impact. The results showed that the strengthening mechanism of TiC particle-reinforced aluminum-matrix composites included fine grain strengthening, dispersion strengthening, dislocation strengthening, and so on. Covering TiC particle-reinforced aluminum-matrix composite coating on the surface of aluminum alloy armature is helpful in improving its ablation resistance. The research results can provide a theoretical basis and technical support for the modification design and performance control of electromagnetic rail armature.

“…As important MMCs, aluminum matrix composites (AMCs) have been widely used in aerospace, defense, and automobiles due to their high strength, stiffness, toughness, hardness as well as low density, good friction, and fatigue properties benefiting from both aluminum matrix and reinforcing particles [1,2]. There are various types of reinforcements in AMCs, such as alumina [3][4][5], SiC [6][7][8], TiC [9], carbon nanotubes (CNTs) [10,11], graphene nano platelets (GNPs) [12,13], metal particles [14], and high-entropy alloy particles (HEAPs) [15][16][17][18][19][20][21][22][23]. Bathula et al [8] blended AA5083 powder with 10 wt% SiC powder by sintering and observed that the hardness of this AMC increased to 280 HV and the elastic modulus increased to 126 GPa.…”

High-entropy alloy particles (HEAPs) can markedly enhance the mechanical properties of metal matrix composites (MMCs). In this study, AA5083/Al 0.5 CoCrFeNi HEAPs MMCs with different HEAPs contents (0, 1, and 3 wt%) were prepared via a stir-casting, and then these MMCs sheets were hot rolled (573 K) and cryorolled (77 K), respectively. The mechanical properties of the MMCs sheets were measured by tensile testing and microhardness test. Additionally, their microstructures were analyzed by scanning electron microscopy and transmission electron microscopy. Results revealed that the ultimate tensile strength (UTS) of the as-cast AA5083/Al 0.5 CoCrFeNi HEAPs MMCs were improved from 203 to 257 MPa by adding 3 wt% HEAPs. And the mechanical properties of the MMCs sheets were improved after cryorolling. After cryorolling with 50% rolling reduction ratio, the MMCs with 1 wt% HEAPs had an UTS of 382 MPa, which was 1.9 times that of the MMCs before rolling. Finally, the strengthening mechanisms of HEAPs and cryorolling on the AA5083/HEAPs MMCs were discussed.
