| Abstract Scope |
In this presentation, we will discuss recent development in in-situ characterization capabilities at sector-1 of Advanced Photon Source (APS). The setup utilizes high-speed area detector to probe material response under extreme thermal cycling conditions. Key features include a novel hybrid photon counting detector that is capable of recording multiple diffraction cones with a frame rate of 250Hz, and up to 1k Hz in ROI mode. Combination of zero background and six orders of dynamic range, the detector is ideal to monitor both major and minor phases simultaneously. The developed setup aims to explore the uncommon space in temperature/time and to better understand the effect of rapid heating and cooling to the microstructure features of engineering alloys. Selected studies on Ti-6Al-4V and Ni-based alloy will be presented to highlight the advantages of the setup as well as limitations. |
