Abstract :Industrial waste is frequently utilized as reinforcing material in aluminum matrix composites insert ignore into journalissuearticles values(AMC); to improve their mechanical qualities. Mill Scale insert ignore into journalissuearticles values(MS);, which is mainly composed of iron oxides, is obtained during the forming process of steel. In the present study, the utilization of MS as a reinforcement material in AMC was investigated. The MS obtained from a steel mill was initially pulverized by high-energy ball milling, and the milling parameters were studied. 20 hours of milling at 800 RPM provided the finest distribution of particle sizes with a dinsert ignore into journalissuearticles values(0.5); value of 1.553 µm. The milled MS was blended with commercially pure aluminum with a ratio of 0-10 wt. % in a high-energy ball mill at 300 RPM for 60-300 min, then pressed and sintered for 2 h at 600-650 °C. It was observed that increasing milling time increases the hardness and lowers the porosity of the samples and increasing the temperature up to 615°C also decreases the porosity values. On the other hand, increasing reinforcement amount increases porosity up to ~10 vol. %, especially over 2.5 wt. %. However, increasing the MS amount results in higher hardness values and lower sample wear rates because of the harder particle reinforcement.
