“…Metal matrix composite materials combine the required properties inherent in each of their components. Aluminum-matrix composites demonstrate significantly better heat resistance, hardness, and wear resistance due to ceramic reinforcements [1][2][3]. The disadvantage of ceramic-strengthened composites is a weak adhesion at the interphase boundary between the ceramic particle and the metallic matrix, which weakens the ductility, toughness, limited strength level, and composites' corrosion resistance [4,5].…”

Increasing the strength of Al-based alloys is an important issue of physical metallurgy and industrial processing. Severe plastic deformation and related extension of solid solubility during mechanical alloying provide an opportunity for significant strengthening due to grain refinement, solid solution, and precipitation strengthening mechanisms. During mechanical alloying, an anomalous increase in the solid-state solubility of alloying elements occurs. The present study focuses on the investigation of the pre-milling treatment to the microstructure, phase composition, and solubility in Al-7.7 Mn-3.5 Cu (wt%) alloy processed by a high-energy ball milling of Al-14.3 Mn-6.5 Cu (wt%) master alloy diluted with Al powder. During milling, the mean granular size decreased to ~5 µm, and a strong grain refinement occurred. According to our TEM and XRD data, ball milling provided a mean grain size of 13–14 nm and a microhardness of 490–540 HV. The lattice parameter of the Al-based solid solution decreased with an increase in the milling time to 7.5–10 h, which suggested the dissolution of the alloying elements, and the lattice parameter increased at a higher milling time of 12.5–40 h, which suggested the decomposition of the solid solution. The XRD data revealed the dissolution of the Al6Mn and Al20Cu2Mn3 solidification-originated phases with a further precipitation of the Al6Mn dispersoids. Pre-milling of the master alloy entailed a significant decrease in the minimal lattice parameter value from 0.4029 nm to 0.4023 nm due to an increase in the Mn solute content from 6.2 wt% (3.3 at%) to 7.5 wt % (4.0 at%) in the studied alloy during high-energy ball milling.

“…The most commonly used methods of manufacture for producing aluminum-based nano particle materials include powdered metalworking, stir molding, compression molding, and frictional swirl manufacturing, among others [9][10][11]. The compression molding method provides a cost-effective, affordable technique that produces nano composite without little pores with a fine particle size [12][13][14][15][16][17][18][19][20][21][22].…”

The superior performance. metal matrix nano-composite substance containing agro-waste reinforcements is the subject of this study's manufacturing and characterization efforts. Composites made using aluminum 7075 as their basis substance with reinforced with rice husk ash (RHA) and Al2O3 are very desirable. The revolutionary composite was made using squeeze casting as the fabrication technique. The overall size % of ash from rice husks on its metal interface was adjusted from 0% to 15% with a constant increase of 5%, while the Al2O3 percentage was set at 3. Many qualities, including hardness, toughness, tensile strength, XRD analysis, XDS analysis, Surface Morphology and wear, define the manufactured composite. According to the findings, the produced cost-effective composite outperforms the raw material in terms of hardness, toughness, and tensile strength.

In this investigation, aluminium-silicon-based alloy (LM6) with the addition of (0, 2.5, 5, and 10%) copper-coated short steel fiber and 5% boron carbide (B4C) element-strengthened composites was fabricated by the stir casting method. Mechanical properties and tribological behaviors of LM6-based hybrid composites were investigated, and microstructures of different castings were examined by an image analyzer. The test was conducted at different loads (10, 20, 30, and 40 N) and different sliding spaces (500, 1000, 1500, and 2000 m), respectively. The results revealed that the sample loaded with 10% of reinforcement recorded the highest tensile strength of 231 MPa. On the other hand, the hardness value increased from 71 to 144 BHN, when 15% of reinforcement was added to the sample. It was also noted that 10% copper-coated steel fiber improved wear resistance up to 50% when compared to LM6. A field emission scanning electron microscope was employed to observe the morphology of the worn surfaces of composites at different sliding distances and load conditions. The hybrid composite revealed that the combination of both short steel fibers and reinforcement of ceramic particles enhanced the mechanical properties, obtaining superior wear resistance.
