Conclusions on the initiation and growth of pits are drawn from optical and electrooptical research of the starting points and well developed pits formed in alkaline solutions in low carbon steel. The pictures show that the first attack is closely connected with dislocations in the metal. After growth of the micro‐pits, the different crystals planes are dissolved in accordance with their energy. Consequently, pits with square‐and hexagonal shape which are bounded by (001) and (011) planes of the α‐iron are created.
