Polycrystalline 3C SiC was irradiated and observed in-situ via Transmission Electron Microscopy with a 20 keV He ion beam at 40 0, 80 0, 10 0 0 and 120 0 degrees C at the Microscopes and Ion Accelerators for Materials Investigations facility. During the 40 0, 80 0, 10 0 0 and 120 0 degrees C irradiations, black-spot damage was observed at 3.1, 1.1, 2.1 and 2.1 dpa respectively. Helium bubbles were observed after 6.3 dpa at 400 degrees C and 2.1 dpa at 800 degrees C, and He platelets were seen after 1.1 dpa at 80 0, 10 0 0 and 120 0 degrees C but not observed during the 400 degrees C irradiation. This work shows for the first time, the preferential nucleation of platelets within stacking faults in 3C SiC. The dependence of He platelet diameter with temperature and dose has also been observed.(c) 2021 Elsevier B.V. All rights reserved.
