“…According to Bhowmik et al [32], by adding both TiB2 and SiC nano additives to the Al 7075 alloy, the tensile strength and hardness improved by about 41.42% and 30.3%, respectively, compared with the unreinforced Al. Moreover, Panthglin et al [33] emphasized that the addition of Zr with a weight percentage of 0.14% to A356-SiC nanocomposite could improve the creep behavior. However, their findings revealed that increasing the weight percentage of Zr higher than 0.14% caused deterioration in the creep strength.…”

Lightweight aluminum alloy components are often used to manufacture a variety of engineering components in many industries. In recent years, researchers have studied the effect of improving the mechanical properties of metal alloys by incorporating nano-carbon into its structure. In this study, the effect of the addition of 0.2, 0.5, and 1 wt% of multi-walled carbon nanotubes (MWCNTs) on the stress–strain behavior and creep phenomenon of an A356 aluminum alloy were studied. The effect of nickel coating on 0.2 wt% MWCNTs was also investigated. Samples were prepared using the stir-casting method. The results revealed that the grain size became finer when MWCNT nano-particulates were introduced. Although the MWCNTs were distributed homogeneously in the A356 matrix, as confirmed by FESEM analysis, there were some agglomerations observed in a specific area with dimensions smaller than 100 nm. Nevertheless, the addition of MWCNTs was found to be beneficial in enhancing the hardness of alloys containing 0.2 wt%, 0.2 wt% nickel-coated, 0.5 wt%, and 1 wt% MWCNTs by 9%, 24%, 32%, and 15%, respectively, as compared with the unreinforced A345 matrix. It was also found that the 0.5 wt% MWCNT-A356 matrix exhibited an improvement in the creep lifetime by more than two orders of magnitude.

In this study, experiments and finite element modeling (FEM) are performed to study the tensile mechanical properties of SiC particle‐reinforced 6061 Al‐matrix composites (SiCp/6061Al) at various volume fractions (VFs) of SiCp. The Young's modulus, yield strength, and tensile strength of SiCp/6061Al display an overall upward trend with the increment of the VF of SiCp. The fracture analysis results demonstrate that the fracture of SiCp/6061Al is a hybrid of matrix fracture, reinforcement fracture, and interface debonding. An algorithm is developed to construct the mesostructure of particle‐reinforced composites, based on the random sequential absorption algorithm. The VFs of the particles of the representative volume element (RVE) model constructed using the novel algorithm are as high as 42%. The tensile mechanical properties of SiCp/6061Al are predicted by replacing the irregular particle reinforcements in SiCp/6061Al with spherical particles in the RVE model. Comparisons reveal that the stress–strain curves obtained via experiment and FEM are highly consistent in the elastic‐plastic stage, which verifies the effectiveness and rationality of the novel algorithm.
