Microfractography of Fish-Eye Fractures in Nitrided Steel

Original language description

The paper presents results of the micro-fractographical study of fish-eye cracks that were formed in plasma-nitrided specimens under symmetrical bending, symmetrical torsion and biaxial in-phase bending-torsion loading regimes. Analysis of the local striation field found near the inclusion in the center of the fish-eye crack together with the local roughness measurements support the hypothesis that the cracks propagate predominantly by mode I micromechanisms. Moreover, the extrapolation of the local crack growth rate curve to the overall fish-eye crack region suggests that similarly to the gigacycle fatigue, the most of the fatigue life is spent on the initiation of the interior microcrack.
