摘要：

A DMLS-AlSi10Mg_200C was subjected to dynamic loading at two strain rates. At 1680 s(-1), an ultrafine substructure formed inside the alpha-Al dendrites due to dynamic recovery (DRV). At 4300 s(-1), continuous dynamic recrystallization (CDRX) occurred, followed by DRV inside the DRX grains with development of nanoscale subgrains.
