The influence of phase distribution and microstructure of the carbon steel on its chloride threshold value in a simulated concrete pore solution

The influence of steel microstructure and phase distribution on the corrosion initiation and chloride threshold value was investigated in a simulated concrete pore solution. Normalizing and cyclic heat-treatment were employed to change the grain size, pearlite, and MnS morphology of the conventional reinforcement carbon steel. The oxidation behavior of obtained microstructures was compared with non-treated steel specimens using the cyclic...
