摘要：

This paper deals with an experimental investigation of the effect of different equal channel angular pressing (ECAP) routes on microstructure, mechanical properties and creep behaviour of pure aluminium. It was found that after four ECAP passes via routes A, B and C the microstructure of aluminium becomes relatively homogeneous. There is little apparent dependence of mechanical and/or creep properties on the processing route.
