Abstract: Differential Speed Rolling (DSR) is a processing technique used to plastically deform magnesium alloys for the purpose of understanding Dynamic Recrystallization (DRX) and its influence on both microstructure and mechanical properties. In this investigation, Mg-based alloys were solution treated and subjected to single-pass rolling for analyzing the role of temperature, strain rate, and processing parameters on the DRX process. Post annealing at temperatures of 350, 400, and 450 ˚C was then performed to evaluate its influence on the static recrystallization process, as well as its influence on microstructure and mechanical properties. Post annealing at both 400 and 450 ˚C at specified times exhibited nearly complete static recrystallization and a significant increase in ductility that nearly doubled as compared to the rolled specimens. This improvement in ductility while maintaining strength enhances mechanical properties necessary to improving the formability of Mg-based alloys. |
