Summary:

This study presents the mechanical characterization studies on 3 wt.% graphene (Gr) filled magnesium matrix composite reinforced with different weight fractions (4, 8, 12, 16, and 20 wt.%) of titanium carbide (TiC) particles. The matrix is AZ91 alloy, and the nano magnesium composite (NMC) is fabricated via a squeeze casting approach. The lightweight NMC is a potential solution for the automobile industry, as it reduces greenhouse gas emissions and contributes to environmental sustainability. Gr is added to enhance the composite's thermal endurance and mechanical strength. Mechanical and corrosion studies are performed as per the ASTM standards. The inclusion of Gr and 16 wt.% TiC tends to enhance the mechanical durability and corrosion resilience of the NMC when compared with other fabricated composites and cast alloys. The uniform dispersal of NC and TiC and better mould properties lead to better strength. Higher inclusion of TiC (20 wt.%) leads to brittleness, thereby decreasing the overall wear loss by resisting abrasive, which lowers the composite's flexibility and strength. The potential mechanism of adhesive wear is shown by the fact that TiC and Gr decrease the intimate contact region between the composite and the EN31 counter-disc. Compared with as-cast alloy, AZ91+3%Gr+16%TiC produced 64.31% higher porosity, 19.50%, 26.69%, 59.45%, and 19.66% higher UTS, micro-hardness, impact, and flexural strength
