英文摘要	National Natural Science Foundation of China [50771088]; Ministry of Science and Technology of China [2009DFA52170, 2009AA03Z101]; The calculation model of the diffusion coefficient under an external magnetic field was presented. The self-diffusion coefficient in the alpha Fe (bcc) phase and the diffusion coefficients of Ni and Co in the alpha Fe phase were calculated. The calculated results indicate that the diffusion coefficient decreases with the decreasing of temperature and increasing of external magnetic field intensity. The kinetics of the gamma Fe (fcc) -> alpha Fe (bcc) phase transformation under an external magnetic field in pure Fe and Fe-1 at.% C alloy were also studied. It is found that grain refinement under an external magnetic field is caused by the increasing of nucleation rate and growth rate as well as the short transformation time. (C) 2011 Elsevier Ltd.
