The process of repetitive upsetting-extrusion (RUE) was used to achieve severe plastic deformation, and its validity in preparing bulk ultrafinegrained materials was demonstrated by experimental investigation on a LY12 Al alloy. The results showed that the microstructure evolution of the alloy due t
