“…Laser shock peening (LSP) induced compressive residual stresses have been found to affect the fatigue crack growth behaviour by delaying the crack initiation and by decelerating the crack propagation rate for aluminium alloys [1][2][3][4], and also for Ti-6Al-4V [5][6][7][8]. For thick Ti-6Al-4V components, the residual stresses introduced by laser peening are typically ~600 MPa near surface, and reduce linearly to a depth of around 2 mm whereupon balancing tensile stresses are encountered [9].…”

“…Laser shock processing is a new surface treatment which was originally developed at the Battelle Columbus Labolatory in the 1970s [5,6]. The principle of LSP is to use a high intensity laser and suitable overlays to generate high pressure shock waves on the surface of the treated material.…”

“…LSP offers advantages such as a higher depth of plastic deformation (than conventional shot peening) and a minimum effect on surface roughness of the substrate. [70][71][72] LSP has also been used to enhance the surface properties like wear and corrosion resistance of Mg alloys.…”
