“…Despite the many advantages of aluminum, the low strength significantly limits its potential applications. Many attempts have now been made to improve the mechanical properties of aluminum by creating nanostructured composites with the addition of two-dimensional materials [7][8][9][10][11][12][13][14]. Thus, the improvement of the mechanical properties of these metallic materials is an issue of high scientific interest.…”

Al is one of the most widely applicable metallic materials due to its advanced properties. However, its main drawback is its strength, which is relatively low compared to ferrous alloys. This issue may be resolved using different approaches. In the present work, a heterostructure of Al substrate with a modified surface with carbon nanotubes (CNTs) was studied. This heterostructure was obtained using the laser-oriented deposition technique. The obtained results showed a slight reduction in the reflectivity of the obtained Al substrate with embedded CNTs compared to pure Al. Additionally, the obtained surface heterostructure showed enhancement in microhardness and higher hydrophobicity. Simulation of the CNT embedding process revealed that CNT penetration strongly depends on the diameter. Hence, the penetration increases when the diameter decreases.

“…As an important part of metal matrix composites, aluminum matrix composites (AMCs) provide a combination of low density, high strength, excellent wear resistance and corrosion resistance for automotive industries and aerospace applications [ 1 , 2 , 3 , 4 ]. Particularly, aluminum matrix composites with different microstructural design by in situ fabrication such as melting methods and spark plasma sintering (SPS) are popular owing to their advantages [ 5 , 6 , 7 , 8 ]. However, the purpose is always to obtain a uniform distribution of reinforcement regardless of which processing method.…”

Recently, heterogeneous structured metals have attracted extensive interest due to their exciting mechanical properties. In this work, an AlN/Al nanocomposite with heterogeneous distribution of AlN nanoparticles was successfully prepared by a liquid-solid reaction method combined with subsequent extrusion deformation, which behaves an excellent synergy of tensile strength and ductility. In order to further reveal the particle distribution evolution and the tensile property response during further deformation, a series of rolling treatments with different thickness reductions under room temperature and 300 °C was carried out. The results show that the yield strength and tensile strength of the composites increase significantly from 238 MPa, 312 MPa to 312 MPa, 360 MPa after 85% rolling reduction at 300 °C. While the elongation decreased from 15.5% to 9.8%. It is also noticed that the elongation and tensile strength of the nanocomposites increases simultaneously with increasing deformation. It is considered that the aluminum matrix strengthening effect accounts for the strength enhancement. The AlN spatial distribution in the matrix becomes more homogeneous gradually during the rolling, which is supposed to reduce the stress concentration between the particle and matrix and then promote the ductility increase.

Recently, the demands of composite materials used in various engineering applications are growing higher because of their outstanding mechanical and thermal properties. This study represents an experimental investigation to determine mechanical properties of Al-based composites materials using Cu and SiC as reinforcement. Al-30-wt%-Cu, Al-40-wt%-Cu, Al-30-wt%-SiC, and Al-40-wt%-SiC composite bars were fabricated using stir casting process to ensure uniform distribution of reinforced elements. The composite bars were prepared into required shape to conduct test for evaluating mechanical properties. Al-40-wt%-Cu shows improved properties such as, hardness, strength, and impact energy absorption than Al-30-wt%-Cu due to more presence of Cu content. Al-30-wt%-Cu and Al-40-wt%-Cu bars showed improved mechanical properties than both Al-30-wt%-SiC and Al-40-wt%-SiC. It is also seen that Al-30-wt%-Cu and Al-40-wt%-Cu showed high hardness, yield strength, and impact energy absorption compared to Al-30-wt%-SiC and Al-40-wt%-Cu respectively. On the other hand, Al-30-wt%-Cu is 3.5% lightweight than Al-30-wt%-SiC and Al-40-wt%-Cu is 2.11% lightweight than Al-40-wt%-SiC. Al-30-wt%-Cu and Al-40-wt%-Cu showed improved specific hardness, specific yield strength, and specific impact energy absorption compared to Al-30-wt%-SiC and Al-40-wt%-Cu respectively. In addition, Al-40-wt%-Cu showed better mechanical properties among the bars.
