英文摘要 | In this work, specimens of 316L stainless steel were implanted with 2.5 MeV He+ ions at constant temperatures of 25 degrees C, 200 degrees C, 300 degrees C, 400 degrees C, 500 degrees C, 550 degrees C, and step-wise variant temperatures of 25 degrees C/600 degrees C and 300 degrees C/550 degrees C, respectively. The dose and dose rate were 2.5 x 10(21) He ion/m(2) and 3.2-3.8 x 10(16)He ion/m(2)/s for each implantation. Bubble structures were investigated with creels-section transmission electron microscopy (XTEM). The temperature dependence of the measured number density and mean size of bubbles exhibited two distinctly different regimes with a transition occurring at 300-400 degrees C. The apparent activation energies suggest that bubble formation is controlled by diffusion of He atoms or He clusters in the high temperature regime, and by an athermal process in the low temperature regime. Cold working of the material had observable effects on bubble formation only in the high temperature regime. Under the varying temperature conditions, bubble formation was influenced strongly by the temperature of the first implantation, even if its dose was low. (C) 1998 Elsevier Science B.V.
