提出了一种新的计算机械搅拌下颗粒间界面温度的方法，并从热力学的角度对温度进行了解释。据发现，界面温度可以估计从C和O之间的反应在界面处。界面温度明显高于容器温度，并取决于摩擦力。摩擦力的增加增加了容器和整个粉末的温度，并且更有效地增加了界面温度。还发现，少量的碳添加是有效地从金属颗粒表面去除氧化物层。
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.
