Hot Compression Behavior and Processing Maps of 6063 Aluminum Alloy Under Medium Strain Rate
A hot compression test was conducted across a range of temperatures (350, 400, 450, and 500 °C) and varying strain rates (0.001-10 s<sup>-1</sup>) to explore the hot compression behavior of the 6063 alloy. Hot processing maps were obtained based on the stress-strain curves. Optimal processing parameters were identified as residing within the intervals of (470-500 °C, 0.01-0.1108 s<sup>-1</sup>), achieving a maximum dissipation efficiency of 0.4, which is of great importance for perfecting hot processing. The microstructure evolution was characterized using an optical microscope and a transmission electron microscope. The initial grains were elongated under compressive deformation, and the density of dislocation rose with increasing strain rate and decreasing temperature. Dynamic recovery serves as the main dynamic softening mechanism during hot compression.
