STUDY ON HARDNESS AND WEAR OF ALUMINUM AA332.0 COMPOSITES REINFORCED MG2SI VIA STIR CASTING: A REVIEW
Aluminum alloy AlSi12CuFe (AA332.0) is use as matrix material and Mg2Si (≤10 – 15 μm) as reinforcement will study. Composites containing of 15wt. % and reinforcement develop by stirring casting route. The ingot alloy melts in a graphite crucible in an electric furnace at 750⁰C ± 5⁰C. This molten stir for 45 minutes and the Mg2Si particles will add inside the vortex during stirring. After completion of the particle feeding, the molten will re-melt in the same temperature for another 15 minutes. The molten finely pours into the metal mould and allowed to solidify at room temperature. Full heat treatments will provide for the samples; solution treatment consist of heating in an electrical furnace at 500⁰C (±1⁰C) for 5 hours and then quenching in water at room temperature. The aging treatment shall be done at 170⁰C for 2 hours. Hardness analysis conducts by following the ASTM E384 – 09 using a Vickers hardness tester. The wear tests conduct using a pin on disc sliding wear testing machine following ASTM G99-05 protocol. The bulk density measure using the Archimedes principle according to ASTM B962 - 13 and porosity measure based on ASTM B963 – 13.
