Abstract
The aim of this work consists in theoretical calculations of the charg e distribution in the crack of an Fe semi-infinite crystal by using th e quantum topological MO-LCAO method in order to formulate general ide as on corrosion mechanisms during the Stress Corrosion Cracking. The m odel suggested describes the cracking by a successive removal of atoms in the direction of a slot formation. It appears that atomic charges are substantially changed in the course of slot formation which can ca use the increase of the reactivity of corrosion particles as the crack is formed.
