In Fe- C- X alloy where X is a susbstitutional element ex. Mn the gamma-> sigma transformation exhibit same morphological characteristic as in plane carbon steels. However the transformation kinetics is slower, since during transformation. In addition to carbon, other susbstitutional elements partition between the two phases. For example in a Fe- C- Mn steel, C and Mn partition to austenite during the growth of ferrite. Since carbon diffusion is faster than manganese diffusion, the overall transformation rate is controlled by manganese diffusion in austenite.
See lessSo diffusion of carbon is faster than manganese in steel.
Manganese has higher diffusivity than carbon in steel.. because atoms with lower melting point possess higher value of D. And melting point of Mn is lower than C.
