| Summary: | 碩士 === 國立中山大學 === 材料與光電科學學系研究所 === 103 === In this experiment, we utilized the research of diffusion couple from Al-Ag-Cu and Ti-Au-Ag system to save the time of aging heat treatment and the cost of materials. With a few alloy specimens, the experiment can be verified the results with high credibility.
Determined the composition of phases by EPMA, the experiment completed Al-Ag-Cu 450 oC and Ti-Au-Ag 800 oC equilibrium phase diagram. There are eight three-phase equilibrium in Al-Ag-Cu system. With correction to the composition of Ag phase at the Cu9Al4-Cu-Ag three-phase equilibrium in the reference, it showed the composition of copper is 10.26 at.% and aluminum is 2.28 at.%. Also, there are six three-phase equilibrium in Ti-Au-Ag system.
