Two samples of the composition Al–15 wt pct Cu and one sample of the composition Al–46 wt pct Ge were processed in microgravity and several samples on ground. In situ X-radiography was performed to observe the nucleation dynamics and microstructure evolution during solidification of the 200 µm thin, disc-shaped samples. The measured dendritic growth rates and observed concentration distributions in the liquid indicate no difference between microgravity and on-ground horizontal experiments, in line with previous observations. 2023-10-05T02:59:05Z 2023-10-05T02:59:05Z 2023 Book https://link.springer.com/article/10.1007/s11661-023-07079-9 https://dlib.phenikaa-uni.edu.vn/handle/PNK/9469 en application/pdf Springer
