文摘

In-depth microstructural evolutions of three LSPed specimens are observed. Novel surface nanocrystallization and amorphization are generated for the first time. Underlying mechanism of surface nanocrystallization and amorphization are revealed. Surface nanocrystallization contributes to the improvement of UTS and ductility of H62 brass.
