The OPARA service was recently upgraded to a new technical platform. You are visiting the outdated OPARA website. Please use https://opara.zih.tu-dresden.de/ for new data submissions. Previously stored data will be migrated in near future and then the old version of OPARA will finally be shut down. Existing DOIs for data publications remain valid.

| Abstract | To investigate the impact of melt conditioning and filtration on intermetallic phases in AlSi9Cu3 µCT studies were conducted. The gained research data show microstructural features like pores (#1) and polyhedral intermetallic phases (#2, #2) in 3D videos. The fatigue crack introduced by ultrasonic fatigue testing (USFT) was segmented from µCT slices by machine learning algorithms of Trainable Weka Segmentation and superimposed with the initial microstructure. The superposition of fatigue crack and initial microstructure is shown for a reference batch specimen (#4) and a melt con-ditioned and filtrated batch specimen (#5). | |

µCT investigations of melt conditioned and filtrated AlSi9Cu3 [1]
To investigate the impact of melt conditioning and filtration on intermetallic phases in AlSi9Cu3 µCT studies were conducted. The gained research data show microstructural features as well as superposition of fatigue cracks with their inital microstructure.
