Abstract
Diffusion is a common phenomenon for the all state of materials. We have developed a new technique for the observation of diffusion in liquid metals by using a fluorescent X-rays analysis and X-rays transmission device. This apparatus makes available the in-situ observation and real-time analysis of diffusion profile in liquid meals. In this study, we applied this apparatus to the measurement of diffusion between liquid Ag and liquid Cu. The diffusion coefficient obtained by this method is consistent with the orders of magnitude of previous results. Technical issues of this method emerged from this study.
