“…High-strength light metallic alloys and composite materials are required for operating at high loads and elevated temperatures [6][7][8][9][10][11]. Due to a good combination of performance, economic, and processing properties, Al-matrix composites account for around 60-70% of all metalmatrix composites [12][13][14][15][16][17][18]. The development of aluminum-based alloys and Al-matrix composites with increased strength is an actual scientific issue that is dictated by relevant industrial requirements.…”

In the present research an Al–7.7%Mn–4.9%Zr–3.2%Cu (wt%) alloy was processed by mechanical alloying (MA) followed by hot press sintering. The microstructure, phase composition, and mechanical properties of the MA granules and sintered samples were investigated. The dissolution of Mn, Zr, and Cu with further precipitation of the Al6Mn phase were observed during high-energy ball milling. In the alloy processed without stearic acid after milling for ~10 h, an Al-based solid solution with ~4.9 wt%Zr, ~3.2 wt%Cu and a ~5 wt%Mn with a grain size of ~16 nm and a microhardness of ~530 HV were observed. The addition of stearic acid facilitated Mn dissolution and precipitation of the Al6Mn phase during milling but led to the formation of the ZrH2 phase that decreased the Zr solute and the microhardness. Precipitation of the Al6Mn, L12–Al3Zr, and Al2Cu phases during annealing and sintering of the MA granules in the temperate range of 350–375 °C was observed, and an additional Al20Cu2Mn3 phase was precipitated at 400–450 °C. Hot-press sintering at 450 °C provided a low fraction of cavities of ~1.5%, the yield strength of 1100 MPa, ultimate compressive strength of 1200 MPa, strain at fracture of 0.5% at room temperature, the yield strength of 380 MPa, ultimate compressive strength of 440 MPa, and strain at fracture of 3.5% at 350 °C. The microstructural evolution during high-temperature deformation on the sample surface was studied and the differences in deformation behavior for the alloys sintered at different temperatures were discussed.

“…There are several mechanical property limits for pure aluminium metal. Using aluminium as a matrix material and reinforcing it with ceramic reinforcement has shown tremendous improvement in its properties [1], which are frequently used due to their ability for customisation as per needs. It is being used in the automobile and aviation sectors [2,3].…”

Due to their effectiveness, lightweight materials have gained international attention in recent decades, with industrial sectors being the primary users of them. Metal matrix composites with nanohybrid reinforcement are a unique composite system combination that enhances the material’s mechanical qualities. In the present article, the mechanical properties of graphene nanoplatelets (GNP) and titanium dioxide (TiO2)-reinforced aluminium 7075 alloy are discussed with varying weight percentages of reinforcements prepared by the stir casting technique. 1 wt.% GNP with and 3 wt.% TiO2-reinforced composites show optimum properties within the range of reinforcement studied, with a 71.9% increment in tensile strength and an 86.6% improvement in microhardness observed; however, elongation is decreased by 31.7% in contrast to the base alloy. Maximum toughness is found to be in 0.5 wt.% GNP with 1 wt.% TiO2-reinforced nanohybrid composites. XRD results show phase analysis. SEM analysis of the fractured surface reveals a mixture of ductile and brittle fractures.

This paper investigated Al-based hybrid metal matrix composites (HMMCs) comprised of Al7075-(T6) base metal matrix doped with SiC+MoS2 reinforced particles for high-strength, lightweight, and wear-resistant applications. Taguchi’s design of L9 orthogonal array (OA) with three process variables having different levels (such as SiC particle (2.5, 3.5, and 4.5 wt.%), MoS2 particle (1.5, 2.5, and 3.5 wt.%), and stirring speed (580, 600, and 620 rpm)) has been selected for fabrication of Al-based HMMCs via an advanced vacuum-assisted stir casting route. The controlled porosity level and dry sliding wear behavior (i.e. wear loss) of fabricated hybrid composites at an ambient temperature of 35°C have been conducted. Besides, metallographic evaluation was inspected through optical microscopy, high-resolution FESEM, and SEM-EDS techniques. Furthermore, experimental outcomes obtained from Taguchi’s design of experimentation were optimized by analysis of variance (ANOVA); and also validated through an artificial neural network (ANN) modeling with a network topology of 3-10-2. The results concluded that a homogeneous dispersion of reinforced particles over the base metal matrix (with controlled both abrasive and adhesive wear mechanisms of worn surfaces). Moreover, a significant reduction in porosity level (up to 29.41%) and wear loss (up to 4.94%) of the proposed hybrid specimen (S4) as compared with an unreinforced specimen (S0). In addition, the predicted values obtained from the ANN model were confirmed in close proximity to Taguchi’s experimental outcomes (with less percentage error), which in turn certified the authentication of the constructed ANN model for the Al-based HMMCs.
