Cast aluminum alloys are widely used in the automotive field for the production of complex engine parts. However, the mechanical properties of heat-treatable alloys (e.g., Al-Si-Mg or Al-Si-Cu-Mg) are negatively affected by prolonged exposure to temperatures higher than about 200 °C. To date, severa...
