“…The toughness of materials decreases with increase of the precipitated amounts and size [40], so the toughness of specimens decreased with increase of methanol. Compared with specimens by PAS with the same addition of methanol during MA, specimens by HP have large precipitates, so their toughness is lower.…”

“…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.

“…The minimal fatigue strength of the reinforced condition with 5 vol % and 3 µm particles can be explained by the further increase of the local stress intensity at the particle-matrix-interface with an increase in particle size [26]. Also, the particle shape essentially affects the stress concentration [14]. Sharp edges of the irregularly shaped particles and slight imperfections of the particle surface cause a significant increase in the internal stresses.…”

“…Tensile strength and fatigue resistance of the composites are also strongly influenced by the aging condition and the matrix microstructure [12,13]. Particle shape [14,15], particle size, and volume fraction [16][17][18][19][20] are critical factors for the mechanical properties and fatigue behavior of the AMCs. Due to an enhanced load transfer from the softer matrix to the stiffer particles, an increase in particle volume fraction and a decrease in particle size lead to a significant increase in fatigue strength [4][5][6][7]21].…”

Abstract:In this work the high cycle fatigue behavior of a particulate reinforced 2124 aluminum alloy, manufactured by powder metallurgy, is investigated. SiC particles with a size of 3 µm and 300 nm and a volume fraction of 5 and 25 vol %, respectively, were used as reinforcement component. The present study is focused on the fatigue strength and the influence of particle size and temperature. Systematic work is done by comparing the unreinforced alloy and the reinforced conditions. All of the material conditions are characterized by electron microscopy and tensile and fatigue testing at room temperature and at 180 • C. With an increase in temperature the tensile and the fatigue strength decrease, regardless of particle size and volume fraction due to the lower matrix strength. The combination of 25 vol % SiC particle fraction with 3 µm size proved to be most suitable to achieve a major fatigue performance at room temperature and at 180 • C. The fatigue strength is increased by 40% when compared to the unreinforced alloy, as it is assumed the interparticle spacing for this condition reaches a critical value then.
