and transmission electronic microscopy (TEM) observations. When pre-ageing temperature is 20℃ (natural ageing), the peak hardness of subsequent artificial aged alloy is lower than that of T6 treated alloy (negative effect), while a positive effect appears when pre-ageing temperature is above 80℃. The size of needlelike β-precipitate in subsequent artificial aged alloy is much coarser when pre-ageing......
