摘要

This research of AZ31 alloy hybrid nanocomposite microstructural and mechanical properties are enhanced by the additions of 2 wt% of alumina (Al2O3) and 1–5 wt% of silicon carbide (SiC) nanoparticles via stir cast process configured with vacuum die cast process. During the process, 1 % Potassium Hexafluorotitanate (K2TiF6) fluoride salt and argon inert gas were used to minimize agglomeration and oxide formation. The actions on microstructural behaviour are analyzed, and it is found that the structure is defect-free, with uniform particle distribution contributing to improved mechanical properties and reduced porosity. The addition of 2 wt% Al2O3 and 5 wt% SiC to AZ31 alloy yields a tensile strength of 197 MPa and 345 MPa, improved impact toughness of 14.8 J/mm2, a good Vickers hardness of 95 HV, and a reduced porosity behaviour of 0.55 %, which is superior to that of the monolithic AZ31 alloy. This is suggested for automotive structural and lightweight components applications.
