摘要：
The point defect production in collision cascades causes fluctuations of vacancy and interstitial concentrations. These fluctuations are shown to affect the void growth kinetics in irradiated metals. In the present paper the analysis of the void distribution behaviour as a function of void sizes is considered. Remarkable changes in void kinetics can exist when the dislocation density is comparatively small. Under conditions determined in the present paper, the cascade induced fluctuations of the void growth rate lead to some decrease in the void density in irradiated metals. Moreover, the spatially inhomogeneous void shrinkage prevails over the homogeneous one. © 1990, Taylor & Francis Group, LLC. All rights reserved.
