“…More than 6 wt% SiC, it was a downtrend due to higher content of SiC leads to separate the particle on high impact load. A similar trend was reported by Sekaran et al 13 during the evaluation of the Al/Mg hybrid composite. Moreover, the composite contained 10 wt% alumina and 6 wt% SiC found good impact toughness compared to all other compositions.…”

“…Moreover, the choice of ceramic and fabrication process was the reason for the higher hardness. 12,13 The higher content of SiC resists the particle movement to the adjusting layer during high indentation. 15 However, the 6 and 9 wt% SiC composite showed better VHN results than all others.…”

“…11 The liquid solidification process was best for magnesium matrix composite preparation due to the simple process, easy to handle, and suited to complex shapes and economics rather than other techniques. [12][13][14] Moreover, the conventional stir casting found slag formation, agglomerated structure, nonuniformity particle distribution, and casting defects. 15,16 The approaches of semisolid stir solved these difficulties: cast, 17 two-stage stir cast, 18 ultrasonic vibration assisted stir cast, 19 and squeeze cast 20 process.…”

With an inherent lowest density and distinct solubility with enhanced mechanical behavior reason, the magnesium alloy composite is extensively used in the auto and aero sectors. The processing of magnesium alloy found micro‐cracks and voids between the oxidation spot, which fails properties. Through the sulfur hexafluoride (SF6) atmosphere, the AZ91D alloy hybrid nanocomposites are synthesized with 10 wt% alumina (Al2O3) and 0, 3, 6, and 9 wt% of silicon carbide (SiC) nanoparticles via a liquid state process with 400 rpm stir speed followed by vacuum die casting. The effect of SiC actions on physical behavior, microstructural formation, and mechanical properties of AZ91D/10 wt%Al2O3, AZ91D/10 wt%Al2O3/3 wt% SiC, AZ91D/10 wt% Al2O3/6 wt% SiC, and AZ91D/10 wt% Al2O3/9 wt% SiC composites are studied and its results compared with cast AZ91D alloy. Due to the actions of SiC in AZ91D/10 wt%Al2O3, the composite density conforms to the rule of mixture, and the void and micro‐cracks are limited (less than 1%) by the impact of the casting process, as evidenced in the microstructural illustration. An effect of 10 wt% Al2O3 and 9 wt% SiC contents in AZ91D facilitates maximum tensile strength of 181 MPa, improved elongation percentage of 2.2%, optimum hardness of 85HV, and superior impact toughness of 21.8 J/mm2, which is higher than the all other compositions.
