<P> The equilibrium behavior of the boundaries separating
the a and y crystalline phases in the copper zinc alloy system
is investigated by measuring the magnitude, the relative
anisotropy and the temperature dependence of the interfacial
energies. A model, consistent with the interfacial energetics,
is proposed and supported by observations of misfit dislocations
at the boundary. The migration kinetics of the y/β interface
are determined for both dendritic and polyhedral morphologies
and the atomic mechanisms of growth are inferred from the.
internally faulted ordered y precipitates. </p> / Thesis / Doctor of Philosophy (PhD)
