When white cast iron is annealed with iron oxide in the same vessel, there occures the decarburisation in the casting as explained in the first report ; and in the second report, the mechanism on the decarburisation of white cast iron at high temperature is principally explained. The change of distribution of carbon in the white cast iron during decarburisation is very complicated commparing in the case of carbon steel, because there are many sources of carbon as temper carbon or free cementite in the matrix of austenite. However, if the properties of these sources of carbon were studied, the migration of carbon in the cast iron could be treated by the diffusion theory of carbon as in the case of carbon steel. And the mechanism of the decarburisation was presumed after many experimental observations and mathematical treatments on the distribution of carbon in the decarburized sample. The effect of graphitization and the chemical composition of white cast iron on the decarburisation was also investigated.
