摘要： We have studied the room temperature and low-temperature electrical resistivities of nanocrystalline Fe-Cu-Si-B alloys with various grain sizes prepared by crystallization of amor-phous material. Experimental results showed that with the reduction of grain size both room temperature resistivity ρRT and residual reaistivity ρ0 of the nanostructured alloys studied increased significantly. Based on the scattering effects from interfaces and lattice distortion, the above results were qualitatively discussed.

Abstract: We have studied the room temperature and low-temperature electrical resistivities of nanocrystalline Fe-Cu-Si-B alloys with various grain sizes prepared by crystallization of amor-phous material. Experimental results showed that with the reduction of grain size both room temperature resistivity $\rho$RT and residual reaistivity $\rho$0 of the nanostructured alloys studied increased significantly. Based on the scattering effects from interfaces and lattice distortion, the above results were qualitatively discussed.
