In order to measure the precise interdiffusion coefficient of carbon in molten Fe-C alloys (Dc), an experiment was carried out for the carbon content of 1.353.44% at 1 4001 650°C by means of a diffusion couple method. The results are summarized as a following experimental equation ;
Dc=exp{-(12 100/T+2.568)+(1 320/T-0.554)[%C]}……(±0.12×10-4) cm2/s and can be shown reasonable through the discussions on the temperature- and the concentration-dependencies of the coefficient.
