Abstract
Laser cutting is widely used in the metal industry, particularly when components of high strength steel sheets are produced. However, the roughness of cut edges produced by laser differs from that obtained by other methods, such as mechanical blanking, and this fact influences the fatigue performance. In the present investigation, specimens of two grades of high strength austenitic steels, i. e. AISI 301LN and TWIP17Mn, were cut by laser and tested in the high cycle fatigue regime to determine t...
