摘要: Abstract The quench sensitivity and time-temperature-transformation (TTT) curves/time-temperature-property (TTP) curves of the 2060 Al-Cu-Li alloy with a 0.68 wt% Mg content was investigated by quench-ending method interrupted technique. It found that quenching depth studied approximately 24 mm. nose temperature in TTP TTT were 365 °C. incubation period corresponding to curve tip 0.3 s. range 260–440 °C. Moreover, higher ascertained be related greater quantity Al-Cu phase containing Zn. restrained Cu, including primary strengthened precipitation T1 θ' phases, subsequent ageing process.
