Nanocrystalline Cu-Ni-P alloys with average grain sizes of 7, 10 and 24 nm were synthesized by means of electrodeposition. The grain size dependences of tensile strength and hardness of the nanocrystalline Cu alloys were investigated. The breakdown of Hall-Petch relation was exhibited in both tensile strength and hardness.
