... corrosion at the crack tip is such that a small radius of curvature (sharp crack tip) is maintained at the crack tip, the crack will continue to propagate, because the local stress at the crack tip is high. High rates of corrosion at the crack tip, which lead to a large radius of curvature (blunt), will...
