چکیده انگلیسی
In this study, hot deformation behaviour of 2024 Al alloy has been investigated using hot pressure test up to 400 °C temperature range with strain rates of 0.001–0.1 s−1. The results show that increasing strain rate, leads to an increase in flow stress. In solid solution state in low temperatures, dynamic precipitation happens during deformation and particles grow dynamically. Dynamic work softening occurs during hot deformation and decreases the stress. In deformation of the samples in annealed state in low temperature no stress loss has been observed during hot deformation. This difference in hot deformation of the samples has been related to precipitation characteristics.
