Chemo-mechanical coupling effect on high temperature oxidation: A review

Abstract

The rapid development in the field of chemo-mechanical coupling has drawn increasing attention in recent years. Chemo-mechanical coupling phenomena exist in many research areas, ranging from development of advanced batteries, biomechanical engineering, hydrogen embrittlement, and high temperature oxidation, etc. In this review, we attempt to provide an overview of the recent advances in chemo-mechanical coupling study on high temperature oxidation. The theoretical frameworks, computational modeling, and experimental studies on this subject are summarized and discussed. The stress-diffusion coupling effect in diffusion-controlled oxidation process, stress-induced evolution of oxide morphology in microscale experiment, and stress-oxidation interaction at crack front for intergranular fracture are highlighted. In addition, potential applications and possible methods via surface engineering for improving oxidation-resistance of high temperature structural materials are briefly discussed.
