摘要：

The low-stress diffusional creep of uranium dioxide of grain sizes in the range 2 to 10 μm was studied over the temperature range 1273 to 1873 K. It was found that the creep behaviour and creep rates agree with a deformation model proposed by Ashby and Verrall. This is supported by microscopic observations of grain and pore movements in a superplastically deformed specimen. © 1979.
