“…The properties of these composites depend strongly on the particle size and particle-matrix interface [20,21]. Reducing the particle size greatly improves the strength of these composites [22]. Accordingly, the present study focuses on the synthesis of Al-based composites using Mg-Al mechanically alloyed (MAed) powder as reinforcement and investigates the effect of particle size on the microstructure and mechanical properties of the composite at fixed reinforcement content.…”

Abstract:The effect of Mg-7.4%Al reinforcement particle size on the microstructure and mechanical properties in pure Al matrix composites was investigated. The samples were prepared by hot consolidation using 10 vol.% reinforcement in different size ranges, D, 0 < D < 20 µm (0-20 µm), 20 ≤ D < 40 µm (20-40 µm), 40 ≤ D < 80 µm (40-80 µm) and 80 ≤ D < 100 µm (80-100 µm). The result reveals that particle size has a strong influence on the yield strength, ultimate tensile strength and percentage elongation. As the particle size decreases from 80 ≤ D < 100 µm to 0 < D < 20 µm, both tensile strength and ductility increases from 195 MPa to 295 MPa and 3% to 4% respectively, due to the reduced ligament size and particle fracturing. Wear test results also corroborate the size effect, where accelerated wear is observed in the composite samples reinforced with coarse particles.

“…Therefore, the hardness of specimens having large particles was lower than that of the small ones [6][7][8][9]. The figures also show that yield stress and compression strength increased with low particle size [10]. According to Eq.…”

Al 2 O 3 is widely used as the reinforcing additive in the metal matrix composites. The influence of Al 2 O 3 particle size on the density, hardness, microstructure, yield stress, compression strength, and elongation of the sintered Al-Al 2 O 3 composites were investigated. In the present study, 10 wt% of Al 2 O 3 powder with three different particle sizes (3, 12 and 48 µm) were used in the production of the samples. Powder metallurgy technique was utilized to obtain more homogeneous Al 2 O 3 distribution across the composites. The samples were cold pressed at 440 MPa, and sintered at 550 • C for 45 min. Results showed that the relative density of the composite was initially increased with decreasing particle size. However, it was decreased with further particle size reduction. It was also pointed out that the mechanical properties of the specimens were increased with decreasing particle size. The grain size and particle distribution homogeneity was decreased with raising the particle size.

“…As expected, the natural ageing of the composite that occurs through hot press process may affect the hardness results. 15) In other words the main reason for this enhancement can be due to the formation of Al (Cu) solid solution and further more heat treatment process that naturally occurs during hot press. 4) Increased dislocation density and microstrain and also grain size refinement due to the milling process which leads to work hardening of the milled materials can be considered as other reasons for that phenomenon.…”

AlMg alloys close to ¢-Al 3 Mg 2 intermetallic phase were processed by neutral gas coverage melting process of pure elemental Al and Mg with the composition of Al40 mass% Mg. Mechanical milling was applied in order to convert the pre-alloyed ingots to nanocrystalline or amorphous alloy. X-ray diffraction and transmission electron microscopy (TEM) tests were carried out to investigate the formation of Al 3 Mg 2 single phase nanoparticle. Having prepared the single phase intermetallic, it was added to the pre-alloyed matrix powder of Al4.5 mass% Cu, in different contents. The effect of the reinforcing agent on the microhardness and wear behavior of the nanocopmosites were studied thoroughly with the aid of press-sinter methodology and quantitative data recorders via pin-on-disk wear test. The results of microhardness tests revealed that the hardness of nanocomposites is significantly improved with increasing reinforcement content with in the matrix. The coexisted wear mechanisms, mainly delamination and abrasive, of the consolidated nanocopmosites were investigated through scanning electron microscopy (SEM) and TEM observations.
