Keywords： 6063 Al alloy

The deformation behavior characteristics of 6063 aluminum alloy were studied experimentally by isothermal compression tests on a G leeble- 1500 thermal-mechanical simulator. Cylindrical specimens of 14 mm in height and 10mm in diameter were compressed dynamically at temperatures ranging from 473 to 723K and at higher strain rates from 5 to 30s 1 It is found that the flow curves not only depend on the strain rate and temperature but also on the dynamic recovery and recrystallization behavior. The results show that the flow stress decreased with the increase of temperature, while increased with the increase of strain rate. The discontinuous dynamic recrystallization (DDRX) may take place at a high strain rate of 20s-1 under the tested conditions. At 30s 1 , the flow curve can exhibit flow softening due to the effect of temperature rise that raised the temperature by about 32K in less than 0.05s.
