SMAs were subjected to two different electrolytes: saturated Ca(OH)<sub>2</sub> solutions with and without chlorides to mimic the conditions in concrete. Two specific heat treatments were applied to the Fe-SMA, which resulted in a change in grain size and precipitation of secondary phases. Furthermore, conventional structural steel, B500B, was utilized as a reference material. The results reveal that the heat treatments did not significantly change the corrosion rates of these alloys in Ca(OH)<sub>2</sub> solution compared to B500B when chlorides were absent. However, the presence of chloride ions suppressed the passivity of B500B and promoted the localized corrosion (pitting and intergranular) of the Fe-SMAs, among which the solutionized alloy showed significantly higher resistance to the pitting.
