As a new magnetostrictive material, Fe-Ga alloy has been used in ships as a displacement sensor. Therefore, it is necessary to study its corrosion and stress corrosion cracking (SCC). This research is the first report of the effect of a magnetic field on the SCC of Fe83Ga17 alloy by slow strain rate tensile (SSRT) tests. The results showed that a parallel magnetic field reduced pitting corrosion. The effect of a magnetic field on V-groove corrosion was different in the different directions. Further, the SCC of Fe83Ga17 alloy was enhanced with a tensile magnetic field and was inhibited with an in-plane or a perpendicular magnetic field.
