Abstract
It has been shown previously that the existing theories on the mode of carbon transfer during sintering of iron-graphite are inadequate to explain the results obtained. From the literature, it is seen that large amounts of oxygen are adsorbed on graphite. Graphite was vacuum degassed at high temperature and sintering experiments using iron-degassed graphite were carried out at 1040°C in hydrogen and in vacuum. These results are also inexplicable by either of the existing theories. Thus it is proposed that carbon transfer from graphite to iron takes place through interparticle contacts after the adsorbed gases, which form a hindrance at the contacts, have been removed. The results of other authors have been explained in the light of this proposal. PM/0211
