This study explores AlZrCe alloy, reinforced with Al₂O₃ nanoparticles, as a potential substitute for Aluminum Conductor Steel Reinforced (ACSR) materials in electric transportation infrastructure, including vehicles, trams, and trains. The Al-0.12%Zr- 0.15%Ce master alloy incorporates Al₂O₃ nanoparticles (0-2%). Fabrication involves homogenization and casting. Research assesses the effects of solid solution treatment and cold rolling on microstructure, electrical conductivity, tensile strength, and hardness. Microstructural analysis reveals reduced alumina particle aggregation with increased thickness reduction, improving tensile strength, hardness, and electrical conductivity. This composite offers promise for high-strength conductor materials, supporting energy and material conservation.
