In-situ Analysis of Heat-Treatment Process of Metallic Materials by Synchrotron-Radiation

摘要

The properties of electric wires made of copper and aluminum are largely affected by the temperature and time of heat treatment. In order to optimize heat-treatment conditions, we have developed an in-situ measurement technique that uses synchrotron X-rays, which have high transparency and intensity. While this technique is expected to reduce measurement and analysis time, its application to actual operation has been limited due to the opportunities for measurement and the time required for data analysis. In this paper, we report new environmental control systems at our synchrotron beamline in SAGA-LS and a newly developed program for the automatic analysis of large amounts of data. We have confirmed that the in-situ measurement of copper and copper alloys is possible and the difference in softening behavior can be analyzed in a short time.
