Paper Abstract

For this paper laser beam cutting-experiments at the grain refined steel T StE 960 V and Q StE 690 TM and at the aluminium alloys AA 2024, 6061, 7474, 8090 were carried out. The hardness profile in the area near the cut edge and the change of the alloy composition were analysed. The measurements of the resulting residual stresses are connected with the observed fatigue properties. The results are compared to those of specimens prepared by plasma-, flame-, and jetcutting.
