Diffusional Phase Transformations in Small Systems

Summary

The aim of the project is to determine experimentally the phase transformations that occur in small particles as a function of particle size, composition, time and temeperature.
The study will peformed using a series of binary and ternary Ag-Au-Cu alloys. Small particles will be prepared by vapor depsotion in a an UHV chamber. The alloy particles will be deposited onto amorphous carbon films supported by a grid and studied using the TEM. Static and insitu heating studies will be performed in the TEM.
