Abstract
Fatigue in low-carbon steel with ferrite and pearlite microstructure has been investigated at different loading conditions through three groups of tests. Two of the groups include tension-tension and rotation-bending fatigue in cylindrical specimens; microstructurally-short surface-crack propagation is monitored by acetate-foil replica technique. The third group of pure bending fatigue tests includes flat specimens preliminary notched by Focused Ion Beam technique. The growth of formed microstructural cracks is examined at: interruptions of each test at a given number of cycles; optical- and SEM-microscopy observation of the corresponding specimen surface. The interaction between the microstructure and crack propagation is revealed.
