This study aims to develop an innovative alloy as a potential substitute for the widely utilized hypoeutectic AlSi7Mg0.3 (A356) alloy, extensively employed in heat-treated structural and performance-critical engineering components. With the aim of achieving this objective, AlSi9Mgx alloys (x: 0.2, 0.3, 0.5 wt%) were produced by low pressure die casting method (LPDC) and subsequently subjected to T6 heat treatments under various conditions, including solution treatment temperature (500, 525, 550°C), aging temperature (160, 180, 200°C), and aging duration (4, 6, 8 h), which were determined using a Taguchi Approach-based experimental design. The heat treatment processes were modelled based on the computational materials engineering (CME) approaches. These simulation results were validated with laboratory-scale experimental tests and characterization studies in an integrated framework. Microstructural analyses pre- and post-heat treatments elucidated the phase morphologies and microstructural transformations, while mechanical analyses revealed the evolution of mechanical properties. The outcomes were rigorously analyzed using the Taguchi Approach, ANOVA, and regression analyses in a statistical manner to investigate the effects of compositional variations in Al-Si-Mg alloys and heat treatment parameters on the microstructural and mechanical properties of the alloys post-treatment. Additionally, the obtained results were systematically compared with the results of previous studies and the AlSi7Mg0.3 alloy, facilitating the systematic investigation of alternative innovative alloys. Furthermore, this study offers a perspective on the reliability and accuracy of software operating based on CME methodologies, substantiating their practical and theoretical implications.
