The results show that the microstructure of LNT-DPD Cu consists of high density of nano-scaled mechanical twins, nano-sized grains and coarse grains with high density of dislocations, which makes the LNT-DPD Cu exhibit a significant high tensile yield strength. Such a deformation structure was attributed to twinning and shearing during the LNT-DPD treatment.
