“…Then, more ș' precipitates were obtained in the composites. Furthermore, because the Į-Al grains in the composites are finer than those in the Al-Cu alloy, the diffusion distance of the Cu atoms becomes shorter during the solution process [22]. Therefore, the finer and more uniformly distributed ș' precipitates were formed in the Į-Al grains during aging process.…”

“…One approach is decrease the size of the reinforcing particles. Some researches indicated that when the size of the reinforcing particles decreases below 100 nm, the strength and ductility of the composites could be improved simultaneously [9][10][11]. But this approach causes non-homogeneous particle dispersion and poor interface bonding.…”

“…The average diameter and thickness of the θ′ phases in 1.3 wt.% TiC/2219 and 1.7 wt.% TiC/2219 composites were about 213 nm, 8 nm, and 287 nm, 8 nm, respectively (Figure 8j,k). Because the grain size of the composite was smaller than that of the alloy, the solution distance of the Cu atom became shorter during aging [30]. As described in Section 3.1, the area fraction of Al2Cu was the largest.…”

In this study, castings of TiC nanoparticle reinforced 2219 aluminum matrix composites with different TiC nanoparticle contents (0, 0.5, 0.9, 1.3, and 1.7 wt.%) prepared using an ultrasound-assisted stirring technology were deformed by multidirectional forging at 510 °C followed by T6 aging treatment. The microstructural evolution and mechanical properties of the 2219 alloy and its composites were investigated and compared. Optical microscopy and scanning electron microscopy revealed that the composite with 0.9 wt.% TiC nanoparticle content possessed finer grains and the lowest amount of Al2Cu phases. The electron backscattered diffraction (EBSD) was used to characterize the sub-grains. The precipitation microstructures of the 2219 alloy and composites with different nanoparticle contents were characterized by differential scanning calorimetry and transmission electron microscopy. It was found that 0.9 wt.% TiC/2219 nanocomposites contained the highest amount of θ″ and θ′ phases with shorter lengths. This might imply that the nanoparticles uniformly dispersed in the matrix could facilitate the precipitation of θ″ and θ′ phases during aging. Thus, the 0.9 wt.% TiC/2219 nanocomposite showed the best mechanical properties. The ultimate tensile strength, yield strength, and elongation of the 0.9 wt.% TiC/2219 nanocomposite increased by 24.2, 46.1, and 37.2%, respectively, compared to those of the 2219 alloy.

“…Hence, a lot of research is conducted on Al matrix nanocomposites, which have larger ratios of strength to weight than that of aluminum alloys. By reducing the size of the reinforcement from the microscale to the nanoscale, many of detrimental effects of micro-sized reinforcements on composites disappear [2]. For example, compared with the conventional composites, the tensile strength and ductility of nanocomposites are simultaneously improved at both room and elevated temperatures [3].…”

To reduce the cost of nanocomposites and improve the dispersion of nanoparticles, Al2O3np/SiCnp/Al hybrid nanocomposites are fabricated by combining liquid-state blowing and ultrasonic-assisted casting. The average grain size of the matrix decreases to 39 μm in Al2O3np/SiCnp/Al, which shows improvements of approximately 118% and 26% as compared to those of Al2O3np/Al and SiCnp/Al, respectively. X-ray Diffractometer (XRD) results confirm the presence of SiCnp and Al2O3np in hybrid nanocomposites. The dispersed SiCnp and Al2O3np are homogeneously distributed in the matrix and no clusters consisting of SiCnp and Al2O3np exist in the microstructure. Theoretical analyses also verify that there is little possibility for clusters to form in the melt. Good bonding between nanoparticles and Al is demonstrated. Neither cavities nor reaction products exist at the interface. The ductility and the strength of Al2O3np/SiCnp/Al are improved. The improvement in yield strength of Al2O3np/SiCnp/Al, in comparison with that of A356, is about 45%.
