摘要	An investigation was conducted on the tensile and compressive properties of commercially pure Al processed by equal-channel angular pressing (ECAP) with two different dies. The specimens along two different directions were cut from the ECAPed billets to study the effect of orientation on the compressive yield strength and the surface deformation morphologies along normal direction (ND) and extrusion direction (ED). It was found that the yield strength of the specimens along ED under tension was lower than that along ED under compression, but higher than that along ND under compression. The surface observations showed that there were some differences in the deformation morphologies under compression along two different directions. Based on the mechanical tests and observations of surface morphologies of ECAPed pure Al, the relationship between shear deformation behavior and tension/compression asymmetry was discussed.
