  The internal oxidation of Sn was investigated to understand the oxidation
kinetics of monophase CuSn alloys. SnO2 particles were characterized by
analytical transmission electron microscopy. The orientation relationship
between SnO2 and Cu was determined with a special emphasis on the atomic scale
structure of Cu/SnO2 interfaces (misfit dislocations and chemical structure).
Habit planes with a pure oxygen plane terminating the SnO2 phase are greatly
favored and large misfits promote the growth of plate shaped precipitates.
