Aluminium alloys are the most promising lightweight materials used in the automotive industry to achieve weight reduction for improving fuel efficiency and reducing CO2 emissions. High pressure diecasting (HPDC) is a fast and economical near-net shape manufacturing method to produce engineering components. About 80% of cast aluminium alloys are currently manufactured by HPDC. The increased demands of manufacturing structural components by HPDC require high strength Al-alloys for the automotive industry; however, the currently available die cast Al-alloys are unable to fulfill this requirement. Al-Mg2Si alloy is known for providing superior high strength through Mg2Si particles but is not applicable in the HPDC process due to severe die soldering issues, limiting its industrial applications. This study focuses on the alloy development for the HPDC process, investigating the effect of excess Mg to modify the hypo-eutectic Al-Mg2Si system and improve mechanical properties. The research combines thermodynamic calculations with experimental methods to analyze the solidification, microstructural evolution, and mechanical characteristics of Al-Mg2Si alloys. Consequently, developing high strength Al-Mg2Si based alloys for the HPDC process is significant for manufacturing quality automotive components.
