Splitting of the phase diagram of a stratified solid solution in micro- and nanosized systems

Intermetallic formation at 425°C in the aluminum–copper system has been studied by scanning electron microscopy using welded diffusion couples. Several Al–Cu phases predicted by the equilibrium phase diagram of the elements and voids taking place in the diffusion zone have been detected in the couples. The predominant phases were found to be Al 2 Cu 3 and the solid solution of Al in Cu, α. The growth of the intermetallic layer obeyed the parabolic law.

Intermediate Phases

The study of diffusion processes in the aluminum - copper system was carried out at the temperature 350 and 520 °C. Special attention was paid on the chemical composition of the system near Al/Cu interface. It was determined that the intermediate phases in the system, corresponding to the equilibrium phase diagram, were not formed at low temperature. At high temperature the intermediate phases forms starting with Cu - rich phases. In both cases supersaturated solid solution of copper in aluminum could be observed near the interface.

Phase Relationships

A tentative phase diagram has been proposed which shows that the system CeF4-CeF3 is essentially eutectic in character. There is no solid solution in the terminal phases. The melting behaviour of the tetrafluoride is complicated by its volatility and by its decomposition into a fluorine-rich vapour and a fluorine-poor liquid. Clarification of phase relationships requires that the system be regarded as portion of the system CeF3-F2.
