摘要：
The corrosion mechanism of low alloy steel exposed to H2S/CO2 environment is investigated. The results show that the mass loss indicates a transition from corrosion acceleration to deceleration during the early stage, the alloy steel with fine grain exhibits good corrosion resistance, it has less mass loss. The relationship of microstructure and corrosion morphology is discussed. A mathematical model is established to predict mass loss based on grey system theory, it can be used to study corrosion behavior. (C) 2017 Elsevier B.V. All rights reserved.
