“…Metallic matrix nanocomposites (MMNC) have recently received extensive attention due to their enhanced mechanical properties such as enhanced hardness, Young's modulus, yield strength, ultimate tensile strength, fretting and wear resistance [1][2][3][4][5][6]. Currently, several routes, such as powder metallurgy [1,2], specially designed casting [3,4], in-situ approaches [5] and mechanical alloying [6][7][8], are available to prepare MMNCs.…”

“…Currently, several routes, such as powder metallurgy [1,2], specially designed casting [3,4], in-situ approaches [5] and mechanical alloying [6][7][8], are available to prepare MMNCs. Among those techniques, mechanical alloying is more common and convenient than other fabrication routes, particularly when discontinuous reinforcements such as particles, whiskers and short fibers/tubes are incorporated [7,8].…”

“…Extension of the composites is decreased by the expansion of alumina/SiC particles. This general pattern was additionally noted for some aluminum framework composites created by different techniques [7,8]. The visual perception of the cracked surfaces demonstrated that constrained plastic misshaping occurred amid elastic tests in concurrence with the deliberate lengthening.…”

Abstract. This study investigates Al 2 O 3 /SiCp-Al composites fabricated by pressure assisted liquidmetal infiltration techniques and modified alumina/SiC particle preforms. The infiltration has been done successfully; Examinations for microstructure, mechanical and physical properties of the composites have been fulfilled. Test results showed that the particle size was the most influential factor in decreasing mechanical properties of hybrid Al 2 O 3 /SiCp composite.

Abstract:In the present work, the tensile properties and fracture behavior of a 2024Al composite reinforced with 10 vol % SiC p and fabricated via powder thixoforming (PT) were studied at temperatures ranging from 25 • C to 300 • C with a strain rate of 0.05 s −1 , as well as the PT 2024 alloy. The results indicated that the tensile strengths of both the PT materials were all decreased with increasing the temperature, but the decrease rate of the composite was smaller than that of the 2024 alloy, and the composite exhibited higher tensile strength than that of the 2024 alloy at all of the employed testing temperatures due to the strengthening role of SiC p . Increasing temperature was beneficial for enhancing the ductility of materials, and the maximum elongation was reached at 250 • C. The elongation decrease over 250 • C was attributed to the cavity formation due to the debonding of the SiC p /Al interface and the fracturing of the matrix between SiC p . The fracture of the composite at room temperature initiated from the fracture of SiC p and the debonding of the SiC p /Al interface, but that at high temperatures was dominated by void nucleation and growth in the matrix besides the interface debonding.
