Abstract
The kinetics of the absorption of nitrogen in liquid iron were studied.
The overall process of nitrogen absorption is devided into such two processes that nitrogen molecules are activated by collision with another nitrogen molecules, and then activated nitrogen molecules dissolve into liquid iron.
Introducing the LINDEMANN'S mechanism, it could be explained that the rate of nitrogen absorption in liquid iron containing surface active elements is controlled by activation process of nitrogen molecules. However, in the range of lower concentration of surface active elements, it is controlled by dissolution process of those activated nitrogen molecules.
The process of nitrogen removal under reduced pressure could be similarly understood by application of this LINDEMANN'S mechanism.
