摘要	A series of ultrafine-crystalline (ufc) pure copper samples with different densities of nano-sized twins were synthesized by means of the electro-deposition technique. Numerous dislocations were induced in the pure copper samples by means of cold rolling. After cold rolling to the deformation degree of 40%, the yield strength of ufc copper sample with high density of nano-sized twins increased from 690 MPa to 850 MPa, while the yield strength of ufc copper sample without twins increased from 230 MPa only to 330 MPa. The difference of strength increment suggests that the copper sample with high density of nano-sized twins has high storage capacity of dislocations.
