Investigating the Microstructure, Tensile Strength, and Acidic Corrosion Behaviour of Liquid Metal Stir Casted Aluminium-Silicon Carbide Composite

The main objective of this investigation is to study the microstructural features and evaluate tensile strength, hardness, acidic corrosion resistance liquid metal stir casted aluminium-silicon carbide (Al-SiC) composite. As reinforcement for Al alloy matrix, SiC particles were added matrix in percentages 0%, 10%, 20%. microstructure Al-SiC composite was studied using optical microscope. effect addition on strength hardness analyzed.. There significant improvements Al–SiC reinforced with 20% compared unreinforced composite, those 14.70% 26.88%, respectively. evolution harder islands ductile aluminium reinforce which enhances A weight loss method used determine rate. samples material immersed HCl, HNO3, H2SO4 solutions immersion times 30 hours, 56 80 hours. It found that % had largest contribution rate 49.86% solution 29.88%, followed by time 8.85% a 29.88% developed 20 wt. showed higher due interfacial region formed greater wt pure alloy.
