The experimental results indicate that there was an obvious difference between the present result and that obtained by Busby (in 1953). It was found that the B diffusivity in γ-Fe increased as Ni added. The diffusivrty of B in Fe-3% Si-B alloy with bcc structure was much slower than one obtained by Busby in α-Fe(1954), however which was much rapid than the results obtained in γ-Fe(with fcc structure).Correspondent: WANG Wendong, Department of Materials Phvsics, University of Science and TechnologyBeijing, Beijing 100083 Key words:  Fe-alloy.
