Effects of Alloying Elements (Cr, Mn) on Corrosion Properties of the High-Strength Steel in 3.5% NaCl Solution

<div>Raman spectra of the nonadherent rust (NAR) formed on REF, 18Mn, and 18Mn5Cr for 56 days in 3.5% NaCl solution at 60°C, where G, L, S, and H represent goethite, lepidocrocite, magnetite (or maghemite), and hematite, respectively. S: spinel oxide, H: <i>α</i>-Fe<sub>2</sub>O<sub>3</sub>, G: <i>α</i>-FeOOH, L: γ-FeOOH.</div>
