Fatigue of steel components occurs when small cracks form and continue to grow to a size large enough to cause failure. Detecting the cracks and determining whether the cracks will cause failure is very important for developing reliability of steel components. We applied a non-destructive method of in- vestigation and focused on the magnetic fields occurring around the cracks. In our previous study, in order to measure the changes in the magnetic flux density, we developed a scanning Hall probe microscope (SHPM) equipped in a GaAs film and observed fatigue cracks at room temperature in air as they grew. we found that the magnetic fields around the crack tips change during crack growth. In order to further understand this phenomena, in this paper, we report the influence of stress conditions on the changes in the magnetic fields around fatigue crack tip in JIS SKS 93 high carbon tool steel.
