Diffusion coefficients of vanadium, cobalt, and molybdenum in molten iron were determined by the diffusion-couple method with the following results:
For Fe-V alloy with vanadium content up to 1.42%
(This article is not displayable. Please see full text pdf.)
for Fe-Co alloy with cobalt content up to 3.9%
(This article is not displayable. Please see full text pdf.)
for Fe-Mo alloy with molybdenum content up to 1.04%
(This article is not displayable. Please see full text pdf.)
The close correlation which was found previously by the present authors between the diffusivity D_j and the standard free energy of solution of the diffusing element in molten iron ΔF_j⁰ has proved to apply to the present results.
