Abstract:
Observations have been made which indicate that the pitting of aluminum is crystallographic. When pure aluminum pits, the resulting morphology of the pit is composed of (100) orientations. Metastable and stable pitting was examined for (100), (110), and (111) aluminum single crystals and polycrystalline aluminum with 99.99% purity. Evidence was seen that the (111) orientation had a higher affinity for initiation and propagation and the (100) orientation had the least affinity for these mechanisms.
