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.
