| Abstract Scope |
This study investigates the combined effects of roll separating force (RSF) and alloy composition on the recrystallization behavior of AA3105 aluminum alloys produced by the twin-roll casting (TRC) technique. Two compositions with varying magnesium (Mg) content—low-Mg and high-Mg—were cast under two distinct RSF conditions: low and high force. Following cold rolling, all samples were subjected to annealing treatments to evaluate recrystallization response. Microstructural characterization revealed that both Mg content and RSF significantly influence the final grain structure. Specifically, increasing the Mg content and decreasing the RSF led to finer recrystallized grain morphologies. This refinement is believed to be related to reduced Mn supersaturation in the matrix, as a greater amount of Mn is incorporated into intermetallic phases under high-Mg and low-RSF conditions. These findings demonstrate how alloy design and process control in TRC can be utilized to tailor the final microstructure of Al-Mn-Mg alloys. |
