The high performance nano-crystal Ni material was prepared by the pulse electrodeposition process; the intensity, composition and the microscopic structure of the nano-crystal Ni material were investigated by various measurements. In this paper, the 1 MeV electron was chosen as the irradiation source to investigate the energy loss of high energy electron in the nano-crystal Ni material and conventional bulk Ni material, and the energy deposition process during the electron irradiation was measured by the absorbed dose tablets. The results show that the grain size affects the energy loss process during the 1MeV electron irradiation seriously. The absorbed dose of 1 MeV electron in the nano-crystal Ni material is lower than that in the common Ni material with the same thickness, which indicates that the energy deposition of high energy electron in nano-crystal metal is lower than that in the conventional bulk metal, and the nano-crystal metal has an advantage of radiation resistance.
