The Influence of Stress on Interstitial Diffusion - Carbon Diffusion Data in Austenite Revisited

Research output: Contribution to journalJournal articleResearchpeer-review


The present paper addresses the influence of chemical induced stresses on diffusion in interstitial systems. This is exemplified by simulations of carbon diffusion in austenite at high temperatures and it is shown that old well established literature data is flawed by the occurrence of composition induced stress. For the technological relevant system of expanded austenite the diffusion can be dramatically affected by composition induced stress.
