New method to evaluate temperature at the interface between particles under mechanical stirring was proposed and the temperature was elucidated from a thermodynamical view point. It was found that the interface temperature can be estimated from a reaction between C and O at the interface. The interface temperature is significantly higher than the container temperature and depends on a frictinal force. An increase in the frictinal force increases the temperature of the container and of the whole powder and increases the interface temperature more effectively. It was also found that a small amount of carbon addition is effective to remove oxide layer from metal particle surface.
