“…Combined with previous studies [11], the optimal hot press sintering process was 490 • C with a holding time of 30 min. Therefore, the composite was subjected to a solid solution plus aging treatment with a view of further improving the microstructure and strengthening the mechanical properties of the composite.…”

“…It can be seen that the particles exhibit an irregular polyhedral shape, and this shape makes the particles produce different thermal stress fields in different directions, which reduces the coefficient of thermal expansion for both the matrix as well as the composite material to a certain extent. Combined with related literature [8][9][10][11], it can be seen that some quasicrystalline intermediate alloys are often added as reinforcing phases to solve the above problems. This is because, among the many particle-reinforced aluminum matrix composites, the quasicrystalline particle-reinforced aluminum matrix composites have unique advantages [11][12][13].…”

“…The coexistence of these larger and smaller particles plays a significant role in enhancing the composite's thermal expansion characteristics. Combined with relevant literature [11], the specific chemical makeup of the 6061 powder is detailed in Table 1. Images captured through scanning electron microscopy (SEM) of the 6061 aluminum powder's morphology are presented in Figure 2a-d, depicting a spherical geometry.…”

This is because, among the many particle-reinforced aluminum matrix composites, the quasicrystalline particle-reinforced aluminum matrix composites have unique advantages [11][12][13]. Firstly, during the process of preparing the composites, because quasicrystals have a certain metal crystal structure (that is, quasi-periodic translational ordering), the quasicrystalline particles can be wetted with the metal liquid [10,14,15], so as to prevent other reinforcers from not being wetted with the metal liquid or from reacting with the matrix metal to produce an undesirable interface [16,17].…”

Al-Cu-Fe-Ce quasicrystalline-reinforced 6061 aluminum matrix composites were prepared through hot press sintering and treated with a solid solution and aging treatments. The influence of the solid solution and aging treatments on the microstructure and mechanical properties of the composites was investigated by XRD, EDS, SEM, and TEM. The results show that using Al-Cu-Fe-Ce quasicrystalline intermediate alloy as the reinforcing phase increases the interfacial areas of the composites and enhances the grain boundary strengthening effect, which is conducive to the improvement of the mechanical properties of the composites. And through the solid solution and aging treatment, the β phase and the Al2CuMg phase belonging to the orthorhombic crystal system, as well as the β″ phase and a small amount of the β′ precipitated phase, were formed in aluminum matrix composites, and these precipitated phases all existed in the composites in a fine and uniform distribution, which ensured the consistency of the mechanical properties of the materials and improved the mechanical properties of the composites. Meanwhile, the deficiency of quasicrystalline particle-reinforced 6061 aluminum matrix composites in age-hardening was solved and the age-hardening capability of the composites was further developed. This method provides a feasible process route for the preparation of high-performance aluminum matrix composites. The application of this process is expected to improve the mechanical properties and durability of this composite and offer a more reliable option for the application of aluminum matrix composites in aerospace, transportation, and other fields.
