The Precipitation Behavior and Texture Modification of Rolled Micro-Alloyed Magnesium Alloy

To widen the application of wrought magnesium (Mg) alloy sheets as an alternative solution for weight reduction in automotive vehicle construction, a rolled Mg-1Zn-0.1Nd-0.2Ca (wt.%) alloy sheet was chosen for this current study. The precipitation behavior, microstructure evolution and texture modification of this alloy were investigated after being subjected to different heat treatment and hot rolling cycles. The results reveal that the effect of micro-alloyed alloying elements was promoted after solutionizing and subsequent hot rolling. The dynamic recrystallization was suppressed compared to the non-solutionized alloy and a significant texture modification effect with a weaken intensity and a broader angular distribution was observed.
