High-resolution transmission electron microscopy (HRTEM) and high-angle annular-dark-field scanning transmission electron microscopy (HAADF-STEM) were applied to investigate the precipitates formed during age hardening at 170 ± 5 °C for up to 48. h of cast A319 aluminium alloy (Al-4.93. wt%Si-3.47....
