“…Aluminum (Al)-based metal matrix composites (AMMCs) are an excellent choice for automotive, aerospace, defense, and nuclear power sectors because of their lightweight and favorable mechanical, thermal, and physical properties. Aluminum (Al)-based metal matrix composites are capable of achieving high strength, high-fatigue resistance, high-wear and corrosion resistance, and good compatibility with various manufacturing processes [5][6][7][8].…”

In this study, Al-Y 2 O 3 nanocomposites were synthesized via mechanical alloying and microwave-assisted sintering. The effect of different levels of yttrium oxide on the microstructural and mechanical properties of the Al-Y 2 O 3 nanocomposites were investigated. The density of the Al-Y 2 O 3 nanocomposites increased with increasing Y 2 O 3 volume fraction in the aluminum matrix, while the porosity decreased. Scanning electron microscopy analysis of the nanocomposites showed the homogeneous distribution of the Y 2 O 3 nanoparticles in the aluminum matrix. X-ray diffraction analysis revealed the presence of yttria particles in the Al matrix. The mechanical properties of the Al-Y 2 O 3 nanocomposites increased as the addition of yttria reached to 1.5 vol. % and thereafter decreased. The microhardness first increased from 38 Hv to 81 Hv, and then decreased to 74 ± 4 Hv for 1.5 vol. % yttria. The Al-1.5 vol. % Y 2 O 3 nanocomposite exhibited the best ultimate compressive strength and yielded a strength of 359 ± 7 and 111 ± 5 MPa, respectively. The Al-Y 2 O 3 nanocomposites showed higher hardness, yield strength, and compressive strength than the microwave-assisted mechanically alloyed pure Al.

“…Regarding the features of each sintering process, it can be concluded that a change in heating method would change the properties of products as grain size, quality of boundaries, reaction products as a function of local sintering temperature and total sintering time, densification behavior and the bonding of the particles [15, 16, 17].…”

In the present study, the effect of heating methods has been studied on the microstructure and mechanical properties of in-situ formed Al 3 V-Al-VC nano-composite. 5 and 15 wt % of VC were added to Al matrix and conventional and microwave sintering processes were performed at 600 °C. While spark plasma sintering process was done at 450 °C with initial and final pressure of 10 and 30 MPa, respectively. The XRD results revealed the formation of Al 3 V intermetallic compound in microwave sintered sample, while in both spark plasma sintered and conventionally prepared specimens, the only crystalline phases were Al and VC. Microstructure studies, demonstrated a uniform distribution of 5wt% VC reinforcement in Al matrix but the 15wt%VC addition led to form agglomerates in all prepared samples. The highest bending strength (275 ± 13 MPa) and hardness (260 ± 13 Vickers) were obtained in the spark plasma sintered sample with 15wt% of VC content.

“…Extensive studies have been done on AMCs to improve their mechanical and tribological properties because of their potential in many applications. So far, different ceramic materials such as Al 2 O 3 [ 5 ], SiC [ 6 ], MgO [ 7 ], WC [ 8 ], B 4 C [ 9 ], ZrB2 [ 10 ], SiC-TiC [ 11 ], ZrSiO 4 [ 12 ], TiB 2 [ 13 ], and TiO 2 [ 14 ] have been used as reinforcing agents within an aluminum matrix.…”

In this research, the mechanical properties and microstructure of Al-15 wt % TiC composite samples prepared by spark plasma, microwave, and conventional sintering were investigated. The sintering process was performed by the speak plasma sintering (SPS) technique, microwave and conventional furnaces at 400 °C, 600 °C, and 700 °C, respectively. The results showed that sintered samples by SPS have the highest relative density (99% of theoretical density), bending strength (291 ± 12 MPa), and hardness (253 ± 23 HV). The X-ray diffraction (XRD) investigations showed the formation of TiO2 from the surface layer decomposition of TiC particles. Scanning electron microscopy (SEM) micrographs demonstrated uniform distribution of reinforcement particles in all sintered samples. The SEM/EDS analysis revealed the formation of TiO2 around the porous TiC particles.
