摘要：

Commercial purity aluminium was subjected to a severe plastic deformation technique called groove pressing at both room temperature and cryogenic temperatures. In both cases, submicron sized grain structures were obtained after deformation; there was no significant difference in microstructures obtained under room temperature and cryogenic temperature deformation conditions.
