Abstract
A model of the dissolution of binary alloys, taking into account the component interaction energy, is suggested. The partial rate constants, as well as the dissolution rate depend on the concentration stepwise, according to the formula n/Z where Z is the lattice’ coordination number. Using these dependences, transitive and steady-state equations of the alloys selective dissolution are derived.
