The post-ECAR aging treatment led to the formation of a nanocrystalline structure with a grain size of similar to 100 nm through the precipitation of fine MgZn2 particles during post-ECAR aging, which pinned the grain boundary motion, and more effectively strengthened the 7050 Al alloy than the pre-ECAR aging.
