Abstract

Self-diffusion of iron in austenite has been studied for 0 to 1.4 wt pet C from 1000° to 1300°C. A large increase in diffusivity and decrease in activation energy with increasing carbon content were observed. The interaction of iron ion vacancies and dissolved interstitial carbon atoms is discussed qualitatively.
