BF images of specimens (a) HT2.4, (d) HT4.8, and (g) HT9.6. The corresponding SAED patterns taken from the non-irradiated area and irradiated area are respectively shown in panels (b), (e), (h) and (c), (f), (i). The SAED patterns in panels (b), (e), and (h) are indexed with the zone axes of [10 1 ¯ 0], [0001], and [10 1 ¯ 0], respectively. (i) With increasing irradiation dose, the diffraction spots in SAED pattern become dispersed at 9.6 dpa.
