In cast iron, the migration of surplus carbon occurs at an elevated temperature, and it seems that the structural change of cast iron in heat treatment is due to this migration of carbon.
The author observed the migration of carbon from the temper carbon in black-heart malleable cast iron, as a simple example, by means of the electric resistance measured at an elevated temperature and microscopic method. After the theoretical treatment of these experimental results, he confirmed that the diffusion of carbon as observed in the case of the carburization of steel occurs in cast iron.
