, and the precipitation kinetics of intragranular T1 precipitates is higher than that during T6 aging at 160 °C. This precipitation behavior is determined by the following two factors during the T8 aging. The first...]. The small plastic predeformation plays an important role in controlling the T1 precipitation. According to the TEM observations, the intragranular T1 precipitation kinetics is much faster during T8 aging......
