文摘

Effects of a strong magnetic field (up to 16 T) on the interdiffusion behavior between Zn and Cu in the Zn/Cu diffusion couple and the growth behavior of the dendrite were investigated experimentally. Results showed that the application of the strong magnetic field caused the reduction of the diffusion layer thickness and retarded the interdiffusion between Cu and Zn. It was also found that the magnetic field coarsened the dendrite and enhanced the growth of the dendrite during the diffusion process. This might be attributed to the damping of convections and modification of the diffusion activation energy under a strong magnetic field.
