Determination of mechanical properties of aluminium matrix composites constituents

Characterization and mechanical properties of α-Al 2 O 3 particle reinforced aluminium matrix composites, synthesized via uniball magneto-milling and uniaxial hot pressing

“…The increasing in compressive strength of the Al+Al 2 O 3 composites may be attributed to different phenomenon. These may include; particle grain refinements, dislocation density increments, the effect of Orowan strengthening mechanism, the load transfer from Al matrix to alumina, full density composites that may reduce the stress concentration regions [30,64,65]. The Young's moduli (E) of the composites and the matrix were calculated using the linear portion of the curves in Fig.12 and the results are summarized in Table 4.…”

Effects of SiC wt% Content on Microstructure and Mechanical Properties of Al/SiC Nano Composite produced by Mechanical Alloying, Sintering and Milling

“…The results consist of different techniques for fabrication of Al/SiC composites. The major methods of fabrications are squeeze casting, metal spray, metal infiltration, laser deposition technology and mechanical alloying, powder metallurgy, and so [19][20][21][22][23][24][25][26][27]. Among them, mechanical alloying have more advantages [25], although there are a lot of problems about uniform distribution of the reinforcement particles in the metal matrix.…”

“…The results showed that nano SiC particles play like a barrier against aluminum formability [28]. The third field of researches concern corrosion behavior of Al/SiC composites [19][20][21][22][23][24][25][26][27][28][29][30][31][32]. They demonstrated that the weight loss of the composites in corrosive media depends strongly on both volume fraction and particle size of nano SiC [26][27][28][29][30][31][32].…”

Nanomechanical properties of magnesium-based hybrid composites with graphite nanofiber and alumina short fiber

“…9 Mussert et al 10 evaluated the hardness and elastic moduli of aluminum-based MMCs with different heat treatment conditions using nanoindentation method. Rodriguez et al 11 applied this technique to determine the hardness and Young's modulus of Al-Li/SiC composite and found an increase in the matrix hardness near the reinforcement and a decrease with the distance from the reinforcement particles. Urena et al 12 investigated the interfacial mechanical properties of carbon fiber/aluminummatrix composites by the nanoindentation technique.…”
