Fabricating micro embossments on the metal surface through spatially modulating laser-induced shock wave

Improvement of Formability and Corrosion Resistance of Az31 Magnesium Alloy by Pulsed Current-assisted Laser Shock Forming

“…Laser shock micro-forming (LSF) technology is a new technology that has developed rapidly in recent years. This, technology has been widely used in research elds, such as material forming, because it does not require the production of high-precision micro-punch molds [7], reduces size effects [8], and improves the material forming performance [9]. At present, more laser shock forming studies have been conducted on copper, stainless steel, and other materials [7][8][9] than on lightweight materials, such as magnesium alloys, and the forming ability of materials with poor plasticity (e.g., magnesium, aluminum, and titanium alloys) and complex micro characteristics is still insu cient.…”
