Abstract

A study of the of laser peen forming of thin stainless steel metal foils (50 μm thick) using a solid-state ps-pulsed laser, emitting at a wavelength of 1064 nm was conducted. The dependence of the bending angle and the radius of curvature on the energy per pulse, the treated area, the distance between lines, and the repetition rate of the treatment is presented. The study also shows that the bending effect is local, and it cannot be scaled by increasing the repetition rate, because the increase in temperature relaxes the superficial stresses previously induced.
