英文摘要: The effect of temperature on the evolution of loops in nickel was investigated under 30 keV He_ irradiation. The size, Burgers vector, and nature of loops were analyzed by a transmission electron microscope (TEM). In addition, the Weibull statistical analysis was introduced to analyze the size distributions of the loops. The TEM results indicate that the sizes of loops increase with increasing irradiation temperature, where they are mainly in the range of 10-30, 20-50, and 30-80 nm at 300, 400, and 500 degrees C, respectively. In the irradiation temperature range of 300-500 degrees C, the size distributions of loops fit Weibull distribution very well, which suggests that the loops tend to grow larger and/ or be merged. In addition, almost all the loops formed under He+ irradiation are the interstitial loops with Burgers vectors b/ a 2 h110i, which is ascribed to the assistance of the He atom on the formation process of loops.
