| Abstract Scope |
In-situ observation of structural evolution is essential for the design of high-performance materials. Coherent X-ray diffraction imaging (CXDI) is an X-ray imaging technique for visualizing the internal structure of the sample with a high spatial resolution of about 10-100 nm. We have developed a dynamic CXDI for in-situ heating experiments, which enable us to observe a selected region of about 10 µm<sup>2</sup> with a spatial resolution of about 50 nm and a temporal resolution of 10 s. As a demonstration, this method was applied to the observation of a Mg-Zn-Gd alloy during isothermal annealing at 700 K. We successfully captured the real-time dynamics of nucleation, growth, and coarsening of precipitates. Furthermore, by combining this method with conventional scanning CXDI, we achieved a comprehensive analysis of structural evolution. Our methodology is a powerful tool for investigating dynamic phenomena in various material systems under practical processing conditions. |
