“…A subsequent thermal process yielded an alloy consisting predominantly of the I phase, alongside a minor presence of the Al 13 Ce 2 Cu 13 phase. Detailed methodologies for the synthesis and thermal processing of the I phase have been expounded upon in earlier scholarly works [13,22]. Figure 1 shows the microstructure morphology of 1Ce-IQC reinforcement with average particle sizes of 120 µm and 60 µm, respectively.…”

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.

This work investigates the evolution of In-Plan Anisotropy during tensile testing and coefficient of thermal expansion measuring of a hot- rolled plate produced from 2014 aluminum alloy treated to T6 condition. These tests were carried out at 0°, 45°, and 90° with respect to the rolling direction, checked, and realized in order to investigate the effect of orientation on its in-plane anisotropic behavior. Results showed that the tensile orientation has an important effect on elongation and stress hardening capacity as compared to the limited effect on yield strength and ultimate strength of the alloy. The in-plan anisotropy factors of both tensile and yield strengths fluctuate in the range of 2.9% to 3.5%; the same factors vary in the range of 27% to 31% for the stress hardening capacity and elongation. Also, the results showed that the expansion orientation has little effect on the thermal expansion of the as-quenched 2014 aluminum alloy at low temperatures as compared to high temperatures. The in-plan anisotropy factor of coefficient of thermal expansion at low temperature fluctuates in the vicinity of 14%, whereas it reaches 47% at high temperature. The in-plane thermomechanical anisotropy was attributed to the microstructure, texture, and precipitation behavior. It was assessed by means of complementary techniques of investigations such as tensile tests, coefficient of thermal expansion measurements, optical microscopy, differential scanning calorimetry, and X-ray diffraction techniques.
