Abstract:	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. wt%Cu). The precipitates at the peak-aged condition have been identified as mainly θ" together with a smaller amount of θ'. It is proposed that the θ" is responsible for hardening at peak ageing at 170 °C of the cast A319 aluminium alloy. © 2012 Elsevier Ltd.
