<p>Synergistic effects of Ti₂AlC (titanium aluminum carbide) reinforcement and aging heat treatment on the microstructure, mechanical characteristics and electrochemical corrosion behavior of induction-melted A390 composites are examined. The A390 alloy’s microstructural examination showed a well-dispersed primary silicon phase, and the inclusion of Ti₂AlC reinforcement produced a synergistic combination of primary silicon and Ti₂AlC that improved the alloy’s mechanical and corrosion resistance qualities. The presence of intermetallic compounds in A390/xTi₂AlC composites was verified by x-ray diffraction. Due to the production of intermetallic compounds and TiC, mechanical tests showed increased tensile strength and hardness with the addition of Ti₂AlC. Tribology investigations of the composites following heat treatment show notable improvements, including 1.5% wear resistance as compared to those without heat treatment. The A390/8Ti₂AlC composite’s steady open-circuit potential values encourage the formation of protective oxide layers, which improve corrosion resistance, according to potentiodynamic electrochemical studies. Additionally, post-microstructure examination indicates that the heat-treated A390/8Ti₂AlC composites have 1% more corrosion resistance and fewer pits and pores. An artificial neural network model has been suggested to effectively forecast the corrosion characteristics. In general, the research offers valuable perspectives on enhancing the characteristics of aluminum alloys for uses that demand superior mechanical performance and resistance to corrosion.</p>
