Influence of Rolling Process and Annealing Condition on Microstructure of Dual-phase Mg-8Li Alloy
This study systematically investigates the microstructural changes of dual-phase Mg-8Li alloy under both unidirectional and cross rolling processes,as well as different annealing conditions,using metallographic microscopy analysis.The results demonstrate that cross rolling can mitigate the alloy's anisotropy,resulting in a more uniform distribution of α and β phases and altering the original banded microstructure.During annealing,as temperature and duration increase,the grain size of the alloy gradually enlarges and exhibits equiaxed features,indicating a significant recrystallization process.Overall,cross rolling improves the distribution of the alloy's microstructure and reduces its performance anisotropy.
