“…Corrosion potential value oscillated a −700 mV for all the experimental samples, however, the lowest average Ecorr wa orded for 6Al-4Mn steel (−733 mV) and the highest for 1.5Al-1.5Mn (−680 mV). Nev less, in comparison to earlier high alloyed high strength steel grades with a similar A ratio, the results show a considerable improvement in the corrosion resistance of th terials [9,11,12,[27][28][29][30][31][32]. For instance, Shih et al [28] reported corrosion rates 580 µm and 570 µm•year −1 for Fe-24.4Mn-9.96Al-0.40C and Fe-30.7Mn-13.03Al-0.44C allo spectively, which were subjected to potentiodynamic testing in 3.5% NaCl solutio guably, the improved corrosion resistance of the studied steels can also be attribu relatively low manganese content (1.5 to 4 wt.%), which decreased the significance soluble corrosion products of manganese [10,12,33].…”

The aim of this paper is to evaluate the influence of small variations in chemical composition on the corrosion resistance and mechanical properties of low-manganese and medium manganese high strength steels. Six different steels with manganese content varying from 1.5 to 4.0 wt.% and aluminium from 0.008 to 6.5 wt.% were subjected to the analysis. The other subjects for evaluation included the effect of aluminium as a replacement for silicon, niobium microalloying and the effect of heat treatment. The effect of non-metallic inclusions on localized corrosion initiation and propagation was also documented. Using potentiodynamic testing, exposure testing, tensile and impact testing, it was found that the improvement in corrosion resistance associated with increasing aluminium content is accompanied by a significant deterioration of the mechanical properties. Niobium microalloying and heat treatment was found to have no quantifiable impact on the anti-corrosion properties. The effect of aluminium content proved to be superior to the effect of nonmetallic inclusions in terms of determining the overall corrosion resistance of the experimental steels.

“…Several corrosion protection strategies have been used including alloying, thermal treatments, and coatings to improve corrosion resistance of the Fe−Mn−Al−C TWIP steels [82,[93][94][95][96][97][98][99][100]. As-quenched, austenitic Fe−30Mn−9Al−(3,5,6.5,8)Cr−1C alloys in 3.5 wt.% NaCl solution showed passivation and lower E corr and E pit values as Cr content increased above 5 wt.%, yet the E corr and E pit decrease for Cr concentration up to 6.5 wt.% and 8 wt.% due to κ-carbide (Fe,Mn,Cr) 7 C 3 [101].…”

Twinning-induced plasticity (TWIP) steels have higher strength and ductility than conventional steels. Deformation mechanisms producing twins that prevent gliding and stacking of dislocations cause a higher ductility than that of steel grades with the same strength. TWIP steels are considered to be within the new generation of advanced high-strength steels (AHSS). However, some aspects, such as the corrosion resistance and performance in service of TWIP steel materials, need more research. Application of TWIP steels in the automotive industry requires a proper investigation of corrosion behavior and corrosion mechanisms, which would indicate the optimum degree of protection and the possible decrease in costs. In general, Fe−Mn-based TWIP steel alloys can passivate in oxidizing acid, neutral, and basic solutions, however they cannot passivate in reducing acid or active chloride solutions. TWIP steels have become as a potential material of interest for automotive applications due to their effectiveness, impact resistance, and negligible harm to the environment. The mechanical and corrosion performance of TWIP steels is subjected to the manufacturing and processing steps, like forging and casting, elemental composition, and thermo-mechanical treatment. Corrosion of TWIP steels caused by both intrinsic and extrinsic factors has posed a serious problem for their use. Passivity breakdown caused by pitting, and galvanic corrosion due to phase segregation are widely described and their critical mechanisms examined. Numerous studies have been performed to study corrosion behavior and passivation of TWIP steel. Despite the large number of articles on corrosion, few comprehensive reports have been published on this topic. The current trend for development of corrosion resistance TWIP steel is thoroughly studied and represented, showing the key mechanisms and factors influencing corrosion processes, and its consequences on TWIP steel. In addition, suggestions for future works and gaps in the literature are considered.
