摘要: Abstract The effects of coverage layer and temperature on the tensile properties surface microstructure H62 brass subjected to laser shock peening (LSP) were systematically investigated. Ultimate strength, elongation rate, in-depth microstructural evolutions three kinds LSPed specimens, including specimens with one layers at room temperature, dynamic strain aging subsequently measured characterized. Special attentions paid nanocrystallization amorphization room-temperature LSP warm technologies for first time. formation mechanisms induced by also discussed completely revealed, contributed improvement ultimate strength rate LSP.
