ملخص

OLiPSE-02 Fe-Cu samples, which were liquid phase sintered under 10-5 torr in microgravity for 20, 30, 60, and 330 min for each composition, were analyzed in this article. The compositions of the samples are 80% Fe/Cu, 70% Fe/Cu, 60% Fe/Cu, and 50% Fe/Cu by volume. The experimental results of distortion and densification were presented. During the microgravity processing, liquid ejection occured for the long duration samples with compositions 70% Fe/Cu and 60% Fe/Cu. Measurements of the weights and dimensions of all the beads were made and their distributions were presented. One of the beads that are about the average weight and size from the 70% Fe/Cu long duration sample was chosen to be mounted, polished, etched, and analyzed under an optical microscope. The iron in the bead appeared as iron grains and its grain size was smaller than that in the mother sample with the same composition. Discussions of the bead and its iron grain formations are provided.
