  12. Abstract The mechanical properties and microstructures of both symmetrically and asymmetrically rolled Al were investigated. The yield strength was ubstantially increased by an improved asymmetric rolling (ASR) process. Nearly equiaxed ultrafined grains with an average size less than 1μm were obtained through the improved ASR with a eduction of 90%. The incrostructure was homogeneous and high-angle boundaries were predominant. The results indicate that this ASR process can be considered as one of most the effective severe plastic deformation methods.
