Abstract: A method for creating an iridescent effect on a surface through formation of wavelets on the source can include using a pulse of laser beams sent to the surface in juxtaposed optical fields of a focusing system. A scanner scans the surface using laser beams along a series of lines that follow each other in a relative direction of travel of the part and of the scanner and a series of lines that lie in continuation of each other in a direction perpendicular to the relative direction of travel. The optical fields overlap in an overlapping area having a width that is twice the diameter of the pulse laser beam up to 2 cm. Two lines lying in continuation of each other overlap at a junction and between the two series of lines follow each other in a relative direction of travel of the part and the scanner.

Abstract: A method for manufacturing a strip having a variable thickness along its length, comprising the steps: an initial strip of constant thickness is provided; homogeneous cold rolling of the initial strip along its length in order to obtain an intermediate strip of constant thickness along the rolling direction; flexible cold rolling of the intermediate strip along its length in order to obtain a variable thickness strip, having, along its length, first areas with a first thickness (e+s) and second areas with a second thickness (e), less than the first thickness (e+s), continuous annealing of the strip. The plastic deformation ratio generated, after an optional intermediate recrystallization annealing, by the homogeneous cold rolling and the flexible cold rolling steps in the first areas is greater than or equal to 30%.
