Pressing Velocity Effects on AA8090 Alloy by Puja Kumari is a document available to read on EtoBox.
This study investigates the effect of pressing velocity on grain refinement in AA8090 Al-Li alloy sheets during repetitive corrugation and straightening (RCS) at 300 °C. It was found that a pressing velocity of 1.5 mm/s resulted in significant improvements in microhardness and tensile strength compared to higher velocities, with notable grain sizes down to 50 nm. The results indicate that lower pressing velocities enhance grain refinement and mechanical properties due to increased strain and dislocation gen
