Experimental study and TiC interfacial action on microstructural and mechanical properties of AZ31 alloy composite made by stir casting route

Abstract

The attention of magnesium alloy nanocomposite prepared with ceramic particle gathering is necessary for structural, marine, automobile, aviation, and defence applications because of its low density, high strength, castability, and ease of recycling. The different weight percentages (0, 2, 4, 6, and 8 wt%) of TiC nanoparticle reinforced magnesium alloy (AZ31) alloy synthesized by stir casting route and find the interface action on microstructural and mechanical characteristics of AZ31 alloy nanocomposites. The scanning electron microscopic images of the composite samples found uniform distributed TiC particles, and more than 6 wt% showed the agglomerated particle. The yield and tensile strength of composite (6 wt% TiC) was increased by 7.64% and 14.6% compared to the cast AZ31 alloy. The maximum hardness (112.5 ± 0.87Hv) was observed by AZ31/8 wt% composite. The tensile fracture of AZ31 alloy nanocomposite with 8 wt% was analyzed, and found poor interfacial action between the AZ31 and TiC. The higher content of TiC leads to brittle nature.
