摘要：

Void growth by grain-boundary diffusion in fine grained materials is examined for the situation where the cavity spacing is greater than the grain size, which, in turn, is greater than the void radius. By solving the governing diffusional equations directly it is demonstrated that the volumetric growth rate of a void is much greater than that predicted by a linear viscous analysis, and by a procedure which ignores the full coupling between void growth and deformation.
