摘要：

Mechanical properties and the deformation behavior of the equal channel angular pressing processed material were investigated by the tensile tests using miniaturized specimens, hardness and by so called penetration tests. The significant increase in yield stress and hardness after equal channel angular pressing was discussed by two strengthening mechanisms. Based on these mechanisms, variations of the yield stress and hardness as a function of the pass numbers were related to the calculated dislocation densities and the average boundary spacing. Also it was suggested that the absorption of the dislocations into grain boundaries would be an effective recovery process for the absence of the strain hardening.
